[R] Could not find function even though I have all necessary packages
Hi,
I am getting the error,
Error: could not find function "createDataPartition"
when I do the code
dataFrame_data <- createDataPartition(data$colA, p=.7, list=FALSE)
even though I have run already
install.packages("caret", dependencies = c("Depends",
"Imports",
"Suggests"))
and
install.packages("caret")
those worked and I then ran
library(caret)
does anyone know why I'm unable to use this function?

Thanks. SessionInfo() did not show it. This is the error when I try library(caret)> library(caret)Loading required package: ggplot2 Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ?munsell? Error: package ?ggplot2? could not be loaded I tried installing.packages("ggplot2") and then I ran library(ggplot2) and it gave me error Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ?munsell? Error: package or namespace load failed for ?ggplot2? On Mon, Mar 28, 2016 at 11:57 AM, Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote:> Post plain text only please. > > Are you sure it loaded?
