Reproducible Research Assignment 2 Analysing stormweather database
Menno Oerlemans
10 september 2017
Synopsis
Storms and other severe weather events can cause significant problems. In this assignment two questions were researched:
1. Across the United States, which types of events are most harmful with respect to population health?
2. Across the United States, which types of events have the greatest economic consequences?
These questions were researched based on the database of U.S. National Oceanic and Atmospheric Administration. The data had to be cleaned and the cleaning has significant impact on the outcomes.
In both cases the answer is Tornado’s. But if you look at the second question and you add different types of floods there is a small margin.
Extended summary
Storms and other severe weather events can cause both public health and economic problems for communities and municipalities. Many severe events can result in fatalities, injuries, and property damage, and preventing such outcomes to the extent possible is a key concern.
This project involves exploring the U.S. National Oceanic and Atmospheric Administration’s (NOAA) storm database. This database tracks characteristics of major storms and weather events in the United States, including when and where they occur, as well as estimates of any fatalities, injuries, and property damage.
In this assignment two questions were researched:
1. Across the United States, which types of events are most harmful with respect to population health?
2. Across the United States, which types of events have the greatest economic consequences?
The following steps were undertaken:
- downloading the data
- reading the data
- cleaning the data based on event types (the cleaning table is in Appendix B)
- calculating the number of fatalities and injuries based on the cleaned event types
- plotting the top ten results (injuries versus event types)
- calculating the economic damage (crop and proporty) caused by the different event types
- plotting the top ten results (economic damage versus event types)
Answer to question 1: the number of fatalities and injuries with Tornado’s are 8 times more than the second event type Heat.
Answer to question 2: the ecomomic damage the Tornado’s are bigest as well. Here there is a definition question: the second an the third event type are Flood and Flash flood. If you add these two up the economic damage is almost equal.

The data is downloaded from the site mentioned in the assignment description: U.S. National Oceanic and Atmospheric Administration’s (NOAA) storm database. This database tracks characteristics of major storms and weather events in the United States, including when and where they occur, as well as estimates of any fatalities, injuries, and property damage.

## (Other): 9The questions are related to the EVTYPE column (types of events). This column has a large diversity caused by the way it was entered. In page 6 of the description of the stormdata (https://d396qusza40orc.cloudfront.net/repdata%2Fpeer2_doc%2Fpd01016005curr.pdf) a table is given with the causes.
The cleaning is done in three steps:
- removing the differences because of lower and upper letters
- replacing special signs with spaces
- replacing the EVTYPE based on an manual made table
A report is given of the cleaning. The table is added in Appendix B.
Clean_orig <- length(unique(Stormdata$EVTYPE))
# removing the difference because of lower and upper letters
Stormdata$EVTYPE <- toupper(Stormdata$EVTYPE)
Clean_orig1 <- length(unique(Stormdata$EVTYPE))
# replace all punct. characters with a space
Stormdata$EVTYPE <- gsub("[[:blank:][:punct:]+]", " ", Stormdata$EVTYPE)
Clean_orig2 <- length(unique(Stormdata$EVTYPE))
# reading the manual made table
Transition <- read.csv("~/R/Course 5/Rename EVTYPE variable.csv", sep = ";")
Transition <- mutate(Transition, EVTYPE = as.character(EVTYPE))
# adding the cleaned EVTYPE
Stormdata <- merge(Stormdata, Transition, by = "EVTYPE")
Clean_orig3 <- length(unique(Stormdata$EVTYPE_NEW))
#Writing the report

First question
The first question is: across the United States, which types of events are most harmful with respect to population health?
The number of fatalities and injuries are in the column FATALITIES and the column INJURIES. In the next plot sum of the number of fatalities and injuries per type of event (top 10) are printed.
Stormdata$Fat_Inj <- Stormdata$FATALITIES + Stormdata$INJURIES
Injuries <- aggregate(Fat_Inj~EVTYPE_NEW, Stormdata, sum)
Injuries <- Injuries[with(Injuries, order(-Injuries$Fat_Inj)), ]
Injuries$EVTYPE_NEW <- factor(Injuries$EVTYPE_NEW , levels = Injuries$EVTYPE_NEW)
g <- ggplot(Injuries[1:10,], aes( EVTYPE_NEW[1:10], Fat_Inj[1:10]))
g <- g + geom_point() + geom_bar(stat ="identity") + coord_flip() + xlab("Number of fatalities and injuries") + ylab("Cleaned events") + ggtitle("Top ten events with the number of Fatalities and injuries during 1950 - 2011")
print(g)
Second question
The second question is: across the United States, which types of events have the greatest economic consequences?
There are two economic consequences in the data:
- Damage to proporties
- Damage to crops
In the discription on page 12 is given that in the column exp belonging to the property and crop damage the exponential factor is given:
- h -> hundred
- k -> thousand
- m -> million
- b -> billion
So the data has to be recalculated and the two outcomes have to be added.
EXP_column <- function(value) {
# h -> hundred, k -> thousand, m -> million, b -> billion
if (value %in% c('h', 'H'))
return(100)
else if (value %in% c('k', 'K'))
return(1000)
else if (value %in% c('m', 'M'))
return(1000000)
else if (value %in% c('b', 'B'))
return(1000000)
else if (!is.na(as.numeric(value))) # if a digit
return(as.numeric(value))
else if (e %in% c('', '-', '?', '+'))
return(0)
else {
stop("Invalid exponent value.")
}
}
property_damage_exp <- sapply(Stormdata$PROPDMGEXP, FUN=EXP_column)
Stormdata$prop_dmg <- Stormdata$PROPDMG * (property_damage_exp)
crop_damage_exp <- sapply(Stormdata$CROPDMGEXP, FUN=EXP_column)
Stormdata$crop_dmg <- Stormdata$CROPDMG * (crop_damage_exp)
Stormdata$Econ_dmg <- Stormdata$prop_dmg + Stormdata$crop_dmgAfter the calculation the results of the economic damage have to analysed. As with injuries the type of events with the top ten damages will be plotted.
Damage <- aggregate(Econ_dmg~EVTYPE_NEW, Stormdata, sum)
Damage <- Damage[with(Damage, order(-Damage$Econ_dmg)), ]
Damage$EVTYPE_NEW <- factor(Damage$EVTYPE_NEW , levels = Damage$EVTYPE_NEW)
g <- ggplot(Damage[1:10,], aes( EVTYPE_NEW[1:10], Econ_dmg[1:10]))
g <- g + geom_point() + geom_bar(stat ="identity") + coord_flip() + xlab("Damage in $") + ylab("Cleaned events") + ggtitle("Top ten events with the bigest damage during 1950 - 2011")
