Hi Toufigh,
R has updated its memory handling in recent updates, so if you are using an
older version of R then updating to the latest version may help. Otherwise
you might try subsetting the plot to reduce the number of plots created.
For example:
# Change the covariate scope
change.xvardef(xpdb,var="covariates") <- c("SEX","AGE","WT")
# then run the plot again:
parm.vs.cov(xpdb)
The scope can also be changed in the classic menu system.
Best regards

Subject: [NMusers] Memory problems with Xpose
Hi,
I am trying to plot model parameters vs. covariates suing Xpose. The data
file is rather large and I get the following message:
In initialize(value, ...) :
Reached total allocation of 1535Mb: see help(memory.size)
2: In initialize(value, ...) :
Reached total allocation of 1535Mb: see help(memory.size)
Error in print(parm.vs.cov(.cur.db)) :
error in evaluating the argument 'x' in selecting a method for function
'print': Error: cannot allocate vector of size 171 Kb
Can anybody offer a remedy?
Thanks!
Toufigh
