I'm running Rstudio 0.98.501 with R 3.02 on OSX Mavericks 10.9.1. I have XQuarts installed. I have loaded these packages:

library(foreign) library(Hmisc) library("ggplot2") library(gdata) library(MASS) library(rms)

Then I do this I do this: model1 <- lrm(Y~xvars, data=devset, x=T, y=T)

val.model1 <-validate(model1, B=50)

I get this error:

Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") [tcl] invalid command name "toplevel".

Does anyone have any tips?

Hej!

I had the same issue and when running the following command in R - as suggested there: http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-notes.html - I realised that there was a remnant tcl/tk 8.5 installation on my system.

system("ls -ld /usr/local /usr/local/lib /usr/local/lib/libtcl*")

drwxr-xr-x 12 root wheel 408 24 Oct 02:21 /usr/local drwxrwxr-x 61 root wheel 2074 30 Oct 22:43 /usr/local/lib -r-xr-xr-x 1 root wheel 4820229 21 Oct 2008 /usr/local/lib/libtcl8.5.dylib -r-xr-xr-x 1 root wheel 1419604 30 Mar 2013 /usr/local/lib/libtcl8.6.dylib -rw-r--r-- 1 root wheel 11072 21 Oct 2008 /usr/local/lib/libtclstub8.5.a -rwxr-xr-x 1 root wheel 4824 30 Mar 2013 /usr/local/lib/libtclstub8.6.a

Removing the old 8.5 files fixed the problem for me.
