[vtkusers] can not find some function of R when use R integrated in vtk

[Li, Wen]

Wes,

R_HOME was set correctly.

We found out the reason but we don't have a very good solution so far.

It is because we have multiple versions of R installed in the operating system.
When we ran R by vtk, it had trouble finding the correct lib path.

Now we are simply running it on a clean operating system and we don't
see the errors and any problem using functions like read.csv().

It will be very nice if someone can give a better solution.

Best,
Wen Li

Do you have the R_HOME variable set to the results of executing "R RHOME"?

Hi, all

We have been trying to use R in vtk to do some statistic analysis for surfaces.

The program was running perfectly when we simply used functions like "mean" and "sum" in our R script.

But when we try to use other functions like "read.csv()", it complains that this function can not be found.

And we see the errors like,

--------------------------------------------------------------------------------------------
Error in identical(env, as.environment(i)) :
  5 arguments passed to .Internal(identical) which requires 2
Error in file(paste(tempdir(), "/Routput.txt", sep = ""), open = "wt+") :
  5 arguments passed to .Internal(file) which requires 4
Error in identical(arg, choices) :
  5 arguments passed to .Internal(identical) which requires 2
-----------------------------------------------------------------------------------------------

Any help or suggestion to solve this problem will be appreciated.

Thank you in advance.
