My first report

A first example of generating a report using R, RStudio and Quarto. The goal of this report is to:

  • Generate a simple report
  • Include some R code
  • Include a figure generated by R

Read in the Data

giss = read.csv("giss_temp.csv")
summary(giss)
      Year          Month          DecDate        TempAnom        
 Min.   :1881   Min.   : 1.00   Min.   :1881   Min.   :-0.860000  
 1st Qu.:1913   1st Qu.: 3.75   1st Qu.:1914   1st Qu.:-0.210000  
 Median :1946   Median : 6.50   Median :1946   Median :-0.050000  
 Mean   :1946   Mean   : 6.50   Mean   :1946   Mean   :-0.009427  
 3rd Qu.:1979   3rd Qu.: 9.25   3rd Qu.:1979   3rd Qu.: 0.150000  
 Max.   :2011   Max.   :12.00   Max.   :2012   Max.   : 0.880000

this just names the data “giss” and gives you a summary.

##Calculations

Now, let’s calculate the mean temp deviation per year, and make a vector of years:

annualTemp = tapply(giss$TempAnom, giss$Year, mean)
years = unique(giss$Year)

And let’s create some plots

First, a histogram of the distribution of all temperature anomaly values.

hist(giss$TempAnom, breaks = 20)

And now a line plot showing the annual temperatures

plot(years, annualTemp, type='l', lwd=2, col=2, xlab="Years", ylab="Temp Anom")
abline(h=0, lty=2)

To show code but not run it….

plot(years, annualTemp, type='l', lwd=2, col=2, xlab="Years", ylab="Temp Anom")
abline(h=0, lty=2)

Other useful options:

  • results: ‘hide’: hide output
  • echo: FALSE: hide R code
  • fig-keep: FALSE: doesn’t display any figures
  • fig-width: 10: alters the figure width (size in inches)
  • fig-height: 7: alters the figure height (size in inches)

You can also stack all of these to use multiple
