Error in X11 (unable to start device PNG)

Question

Hello.
I have a problem with running embedded R script.
First script runs fine:
begin
sys.rqScriptCreate('Example1',
'function() {
ID <- 1:10
res <- data.frame(ID = ID, RES = ID / 100)
res}');
end;
The second one is not so fine:
select *
from table(rqEval(NULL,
'select 1 id, 1 res from dual',
'Example1'));
ORA-29400: data cartridge error
Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, :
unable to start device PNG
ORA-06512: на "RQSYS.RQEVALIMPL", line 57
29400. 00000 - "data cartridge error\n%s"
Can anyone help me?
Thanks.

SELECT PVALUE
FROM TABLE(rqEval(
CURSOR(SELECT 1 "ore.connect", 0 "ore.graphics" FROM DUAL),
'select 1 pValue from dual',
'RF_TTEST_PVALUES'));Hi,
Thats is very good. Is it a way to do it in R client to avoid following error?
Example:
ORE> library(ORE)
ORE> ore.connect(user="rquser", password="pass", sid="TEST", host="r2151", port=1525, all=TRUE)
Error in .oci.GetQuery(conn, statement, data = data, prefetch = prefetch, :
Error in try({ : ORA-20000: RQuery error
Error in X11(paste("png::", filename, sep = ""), g$width, g$height, pointsize, :
unable to start device PNG
ORA-06512: at "RQSYS.RQEVALIMPL", line 104
