[R] Error: ReadItem: unknown type 98, perhaps written by later version of R

[Aldi Kraja]

Hi,

Here is a solution for this type of error:
Error: ReadItem: unknown type 98, perhaps written by later version of R
Execution halted

Created a script file under the directory where the pgm-s and data 
reside and ran there

./script.sh

where script.sh had the following lines
R CMD BATCH ./dc19at1.R ./dc19at1.out
sleep 3
R CMD BATCH ./dc19at2.R ./dc19at2.out
sleep 3
...
etc

The programs ran with no problem.

So what I did is eliminated the full path let's say
R CMD BATCH /a/b/c/dc19at1.R /a/b/c/dc19at1.out
which did not work through bsub or at the command line in a remote server.

I am not sure what is the "type 98 error" meaning in R?
Anybody knows where the R error types are described?

TIA,

Aldi
