How do I install an R package from zip?

I have read a bunch of questions and sites about installing an R package from a zip, but I cannot get it to work properly. I am running the command:

install.packages("caret_6.0-24.zip", dependencies = c("Depends", "Suggests"))

It looks like it works, it gives me this repsonse:

inferring 'repos = NULL' from the file name
package ‘caret’ successfully unpacked and MD5 sums checked

The problem is that after I've installed the package, it doesn't seem to do anything. For example, I run this command and get the response on the second line.

inTrain <- createDataPartition(y = data$class, p = .75, list = FALSE)
Error: could not find function "createDataPartition"

Any ideas or suggestions?

Have you used require or library to load the package? Installing just downloads and places the files in a specific directory that can be later loaded from. Try:

library(caret)

Or

require(caret)
