Sometimes, I use install.packages() followed by library(some name) to get in some data sets. At other times, I git to do install.packages(“specificname’) to get in the data set. What’s the difference?
Thanks.
You use for install the packages. Not for load data set.
If you want a specific data set of a library, first you need load this library and next the data set.
If you dont load the library the data set dont appear available.
install.packages('faraway')
library(faraway)
data(seeds) # data set of this library.
seeds
# germ moisture covered
# 1 22 1 no
# 2 41 3 no
# 3 66 5 no
# 4 82 7 no
# 5 79 9 no
# 6 0 11 no
> install.packages()
Error in utils::install.packages() : no packages were specified
If your scripts have install.packages()
with nothing in the brackets, then its just a waste of text, as it achieves nothing.
