Dear all, I have a Mac, OSX 10.7.5, run R 3.1.2 (2014-10-31) and Matlab R2013a (8.1.0.604).
I try to call R from within Matlab to run a function in Batch mode.
To do this, I followed this example:
From: www.mathworks.com/matlabcentral/newsreader/view_thread/163726
In an m-file you would have:
~~~~~~~~~~~~~~~~~~~~~
data = sum(rand(100), 1);
csvwrite('data.csv', data(:)); % Write as a column
system('R CMD BATCH calc.R outputForDebugging.txt');
testResults = csvread('testResults.csv');
testResultsStruct = struct('W_statistic', testResults(1), 'p_value',
testResults(2))
~~~~~~~~~~~~~~~~~~~~~
In the calc.R r-file you would have:
~~~~~~~~~~~~~~~~~~~~~
data <- read.table("data.csv", header = FALSE, sep = ",")
results <- shapiro.test(data$V1)
results2 <- c( results$statistic[["W"]], results$p.value )
write.table(results2, file="testResults.csv", sep = ",", col.names = FALSE,
row.names = FALSE, qmethod = "double")
~~~~~~~~~~~~~~~~~~~~~
Now, the R-Part in itself works fine. If I open R and run the calc.R-Script
everything works. If I run the calc.R in Batch mode from the terminal,
everything works.
However, if I call R from within Matlab using the system command, I get the
error:
Error in dyn.load(file, DLLpath = DLLpath, ...) :

Beim Start - Warnmeldung:

It appears that R fails to load some objects. However, I don't understand why
this only happens if I call R from Matlab, not when I start R by itself or use
the terminal to start R.
I already installed R new, but it did not help.
Can anyone enlighten my on this matter?
Thanks a lot!
Julian
