Hello,
In my simulation I use the try()-function to catch possible errors when
fitting models. I run the simulationon a Linux-server using the command
" R CMD BATCH nameOfFile.R &". When executing the code as batch-job I
get the problem that the execution is halted without giving an error
message. But when I run the code interactivly the error is catched by
try() as it would be expected.
The problem is somewhat strange as it only occurs when the code is
executed as a batch-job and when the package "Matrix" is loaded.
I wrote a small example reproducing the error. (In my code the error
occurs in mgcv:::fixDependence, which looks like the code I'm using
below in order to get a small reproducible example. I realized that the
code makes no sense...)
######################################
library(Matrix)
R <- matrix(abs(rnorm(25)), 5, 5)
r0 <- r <- nrow(R)
# while-loop produces error that should be catched by the function try()
try(
while (mean(R[r0:r, r0:r]) > 0) r0 <- r0 - 1
)
# so "Hello" should be printed
print("Hello")
######################################
I use R version 2.15.1 (2012-06-22) on a x86_64-pc-linux-gnu (64-bit)
platform.
I would be grateful for help.
