I would suggesting using "" instead of NULL for rz, throughout this code.
(I would also suggest making sure the code can be copied into R without
causing a syntax error before posting the request for help.)

To reframe the problem ... the issue is not with the function nchar() (or
whatever), it's with the input value rz being null. I suggest you build
into the loop whatever actions/outputs you want when rz is NULL.
for (i in 1:10){
if (is.null(rz)) {
# do something here
} else {
if (nchar

Hi,
In case this is helpful for anyone, I think I've coded a satisfactory
function answering my problem (of handling formulas containing 1-level
factors) by hacking liberally at the model.matrix code to remove any
model terms for which the contrast fails. As it's a problem I've come
across a lot (s
The one you cite must have been due to fat-fingering (send instead of delete),
but there was a later followup to David, w/copy to r-help.

Q4 is highly dependent on the types of problems that are to be addressed by the
user. Large problems may need more RAM, disk space, or separate database
facilities to support the problem at hand, but there is nothing about R itself
that requires these optional support resources.

Hello, I have following problem in loops. It occurred to me multiple times
bellow is an example. Inside if() I have sometimes function f(x) which may
return integer(0). If I test f(x)>1 and f(x)=integer(0) I get error. Maybe
it can be solved more eloquently without loop or swithces. I don't know.

Dear Support Team,
Our company needs a new software for scientific statistics.
We have looked at your software " R Project”
I would ask you to provide information on the following criteria:
1) Is the R-Procejt software terminal compatible? We have deployed Citrix. Are
there any Server modules

Hi
Hm. Strange that you did not use any non-base package yet.
install.pakages("effects")
library(effects)
shall do the trick.
And if you are in installing, you could renew your R version which is rather
old.
