[R] Cannot Connect to R server

My RStudio has a wired problem. When I run library(the package I have successfully installed), RStudio has no response. After endless waiting, an error message comes out saying R cannot connect to the R server. Both my R and RStudio are perfectly updated. Anyone can help me out? I appreciate. --

The easiest way is to find out what the actual projection is, and reconstruct a sensible representation of the grid. Usually you have to guess, but it's possible to figure out. You *can* plot by building a proper mesh in longlat, but my preference is full rescue. You need to know the projection an
