Unable to load package in R

Question

Since yesterday I can’t download some common packages used, for example. reshape2and stringrthrough the library team.

Step to reproduce my problem:

1) Start a new session on the Rstudio server (version 0.99.467). I also kill active sessions on the Rstudio server.

2) Run these codes

library(ggplot2)
library(stringr)

3) Get an error message:

Error in unloadNamespace (package): namespace 'stringr is imported' reshape2, so you cannot upload Show trace

Repeat with Debug

Error in library (stringr): "stringr" version 0.6.2 could not be unloaded.

But I do not get an error if stringrloading up to ggplot2. How do I fix this problem. Thanks for any suggestions.

I may have to upgrade R to 3.2
