To do that, you send the install.packages() function a vector or list of package names.Ī vector is a list of objects.
CANNOT INSTALL R STUDIO INSTALL
You can also install multiple R packages at the same time. Advanced - Install Multiple Packages at Once Keep in mind that not all R packages are secure. However there are other places where you may install packages from including:ĭata tip While some R packages are just fine to use. When you call install.packages("package-name-here") you are actually downloading the packages from CRAN. R packages are most often found on the CRAN repository. When you load a library in R, you are telling R to make all of the FUNCTIONS available in the package (think of functions like tools that perform tasks - for example plot()) available to you in your code. We will see how calling a package works in a later set of lessons. However, when we use ggplot2 to plot, we will have to call it.
CANNOT INSTALL R STUDIO CODE
Thus we won’t have to call these two packages in our code in this lesson. In our case, the knitr and R Markdown packages load buttons and options within the R Studio environment that we can use. But you do need the quotes when you install a package. Note that you don’t need to use quotes around the package name when you call it using the library() function. # load libraries library ( knitr ) library ( rmarkdown ) library ( ggplot2 )
