Any idea why I keep getting the message below in R?
Error : .onLoad failed in loadNamespace() for 'Rcpp', details: call: .External("class__dummyInstance", ...) error: C symbol name "class_dummyInstance" not in load table Error: package 'Rcpp' could not be loaded
I have tried everything and it seems that nothing can fix this problem. The machine used is not mine but a client's. There are a lot of restrictions from IT and they have roaming profiles. I installed the 32-bit and 64-bit, just the 32-bit and just the 64-bit but nothing. The machine has Windows 7 64-bit.
So any ideas?
