Hi,
If x is a data frame, then x$getmean will try to get the vector named
getmean in x. You put "()" after x$getmean. I think r is confused about
it. It appears that you want to call a function named getmean().

Indeed, there are _many_ side effects to this and you really

HI all-
I have used this .fun in S+ without a problem however, in R when I run this
code to generate multiple graphs:
trendplot<-function(datafr,dataf2, abbrev="", titlestr="",
devname="s",filen="",styr=1990,endyr=2012) {
if (!is.null(dev.list())) {dev.off()}
dataf<-datafr[datafr$abbrev==abbrev

I have got the following statement:
*> overview.domains$sample.var <- aggregate(migr$amigo.migr,
by=list(siruta=amigo$siruta), var)[,-1]/overview.domains$n.i.*
*Error in migr$amigo.migr : $ operator is invalid for atomic vectors*
What should i do to solve this error?
Thank you.
Kind regards,

It would have been helpful if you had sent your R code of how you
constructed the sab object.
If you have a data.frame, the subset command you are having trouble with
should work fine. See below.
# Working Example
sab = data.frame(group=c('Group A', 'Group A', 'Group C', 'Group B', 'Group

Dear all,
Starting from a recent version of R, the $ became "unusable" on atomic vectors,

I can of course do

- but that requires more typing (5 characters rather than 2).
