library()
get_help()
docs
The library()
function comes with R
and is part of the Base R
{base}
package.
We use this function to load libraries into the R session. This function will not install libraries for you, which is (usually) done with the {base}
R function install.packages()
.
Sometimes libraries show messages when they load to tell you about some aspect of its behavior. These are generally not errors!
# Load the ggplot2 library
library(ggplot2)
# You can also use quotes - it makes no difference
library("ggplot2")
# If you try to load a library that isn't installed OR you have a typo,
# you will see this error message:
library(definitely.a.fake.library)
## Error in library(definitely.a.fake.library): there is no package called 'definitely.a.fake.library'
