MODIFYING DATA:

Data

The atmos data set resides in the nasaweather package of the R programming language. It contains a collection of atmospheric variables measured between 1995 and 2000 on a grid of 576 coordinates in the western hemisphere. The data set comes from the 2006 ASA Data Expo.

LISTS:

Some of the variables in the atmos data set are:

  1. temp - The mean monthly air temperature near the surface of the Earth (measured in degrees kelvin (K))
  2. pressure - The mean monthly air pressure at the surface of the Earth (measured in millibars (mb))
  3. ozone - The mean monthly abundance of atmospheric ozone (measured in Dobson units (DU))

FORMULAS:

#$ put formula on same line as text #$$ puts formula on middle of a new line

You can convert the temperature unit from Kelvin to Celsius with the formula

\[ celsius = kelvin - 273.15 \]

And you can convert the result to Fahrenheit with the formula

\[ fahrenheit = celsius \times \frac{9}{5} + 32 \] ## Cleaning

To analyze this data, we will use the following R packages:

#code chunk #1
library(nasaweather)
library(tidyverse)
1:20 + 1:6

For the remainder of the report, we will look only at data from the year <!—code chunk 3: Insert inline code to reference year –> . We aggregate our data by location, using the R code below. r
