TLDR; Install and/or Update R and R Studio on your computer
Sometimes it is impossible to summarize everything that needs to be explained in an Instagram post. So I've decided to include them here as well. Hopefully with more thorough explanations.
The overall release schedule for R is to release updates every year in the spring, with patches issued as needed. You can plan on updating R at least once a year. However, updating R isn't always easy. These are the steps I follow in to update R on my machine. It might not be the best, but it works for me.
The following line of code will create a list of all the packages you've installed in R. This is a jumbled bit of code, you can dissect it if you want.
I generally run this in my documents folder of my computer, that way I know where the saved file goes. You can change where this file is saved by changing the
file parameter in the
pkgs <- installed.packages()[, 1][!(installed.packages()[, 1] %in% installed.packages(priority = 'base')[, 1])] save(pkgs, file = 'installed_packages.RData')
After running the above snippet of code I'll exit R Studio and install the newest version of R. Once R is installed run the following line of code to install all of your packages.
Note: the current version of these packages will be installed, this may have unintended consequences. If you experience issues you can specify the version you wish to install, and retry the installation of the package causing issues.
R & R Studio Setup
General R and R Studio setup tips if you are attempting to install R for the first time.
The current (3.6.0 as of May 6, 2019) installation file for R can be found here: https://cran.r-project.org/. Select the installation for your system.
Install R Studio
The current (1.2.1335 as of May 6, 2019) installation file for R Studio can be found here: https://www.rstudio.com/products/rstudio/download/#download. Select the installation for your system.
Customizing Your IDE
There are many options for to customize your environment. Go to the
Tools > Global Options menu option. Here you can change the appearance and behavior of R Studio.
Every time I open R I want a fresh environment to work in. On the General tab of the Global Options menu uncheck the
Restore most recently opened project at startup and
Restore previously open source documents at startup under the R Sessions section. Uncheck the
Restore .RData into workspace at startup and choose the Never from the drop down for
Save workspace to .RData on exit.
I prefer a dark IDE, select the Appearance menu item, and in the
Editor theme box choose a dark theme (or different theme). You'll see a preview to the right.
If you have a fresh install the following packages are good to install.
tidyverse- installs many packages that make working in R a lot more expressive
sf- for spatial data analysis, newer packaged for spatial data
raster- for raster data
viridis- color palettes for plotting continuous data
rcartocolors- color palettes for mapping, diverging, categorical data
sp- the original spatial packages, quickly becoming obsolete because of the
sfpackage. You'll still need some of the functions from
Install these with the following command
install.packages(c('tidyverse', 'sf', 'raster', 'viridis', 'rcartocolors', 'sp'))
