Getting "lazy load database corrupt" errors in R

Question

I have had some problems with R recently. I was trying to install nnet which seemed not to be working. I followed the advice on this question and used remove.packages () and unloadNamespace() on 'car', 'effects' and 'sjPlot'.

Problems trying to install package in R

This was successful in installing nnet, however now im unable to reinstall the three packages. After reinstalling each package, r states:

library(sjPlot)

Error in get(method, envir = home) : lazy-load database '\xxx/SSD_Home_Data_O/xxx/My Documents/R/win-library/3.2/car/R/car.rdb' is corrupt

2: In .registerS3method(fin[i, 1], fin[i, 2], fin[i, 3], fin[i, 4], : restarting interrupted promise evaluation

3: In get(method, envir = home) : restarting interrupted promise evaluation

4: In get(method, envir = home) : internal error -3 in R_decompress1 Error: package or namespace load failed for ‘sjPlot’

Any ideas how to fix this? Im a bit worried as I really need to use sjPlot in particular

Thanks for the help

Have you completely removed and re-installed all affected packages? – Blancmange

As far as im aware I have yeah. Do I need to manually go into the folder and delete it? – Fledgling
