Problems trying to install package in R

Question

I am having problems trying to install the nnet package in R. The download seems to be ok, but when I load the library it states

namespace ‘nnet’ is imported by ‘car’, ‘effects’ so cannot be unloaded

In addition: Warning message:

package ‘nnet’ was built under R version 3.2.5

Error in library(nnet) : Package ‘nnet’ version 7.3.11 cannot be unloaded

I tried reading other topics which suggest using remove.packages on car and effects. However I tried this and I am still unable to install

Thanks for the help

Try unloadNamespace('effects') before trying library(nnet).

Although now I have another problem. I had to uninstall car and sjplot to install this, but now both say >Error in get(method, envir = home) : >lazy-load database '\\[xxx]/My Documents/R/win-library/3.2/car/R/car.rdb' is corrupt – Ross M May 05 '16 at 09:47
Also says the same for sjPlot – Ross M May 05 '16 at 09:48
This is the error you get when you try to `install.packages('car')`? – Gaurav Bansal May 06 '16 at 17:00
Hi Gaurav. No this is the error I get when I try library(sjPlot) – Ross M May 10 '16 at 13:13
Try removing all affected packages like so: `remove.packages('car')`, and then reinstalling them. – Gaurav Bansal May 10 '16 at 15:48
