what is the function naming convention?
...tc)
- many are dotted: as.complex, as.data.frame.array, merge.data.frame, write.dcf (etc)
The manual "Creating R Packages" states that it depends on the classes and instances. I couldn't find more hints.
And there's more:
- using underscore characters: check_tzones, Cstack_info, R_system_version (etc)
- using interCapping: closeAllConnections, rawToChar, rowSums, toString, tryCatch, writeLines (etc)
- using dots and intercapping: as.Date, julian.Date, toString.default (etc)
So, an entire zoo of function names.
Did I miss a system, or is it arbitrary (w...

Win 32-bit, stack size problem with third party software?
...e has been increased to 64MB (it has been 10MB
since the days of 32MB RAM systems)."
Furthermore, I found a discussion for RStudio which looks very similar to me:
http://support.rstudio.org/help/discussions/problems/4126-rstudio-v-and-v0963
31-running-with-rbbg
I checked the C stack size with Cstack_info() and saw that
in the RGUI 2.15.2 it is 67108864,
in the RGUI 2.15.1 it was 10485760
and in RStudio using R 2.15.2 it is 20971520.
Maybe also this message is related:

Am I?m right that the problem is related to the increase in C stack size?

using randomForest() with matrix() as input results to an Error: protect(): protection stack overflow
...() using this command:
rf = randomForest(classes~., data=as.matrix(train), mtry=5, ntree=2000,
importance=TRUE)
and it always results in *Error: protect(): protection stack overflow.*
As you can see, I have already turned the training dataset into a matrix
but this didn't fix anything.

SEXP i/o, .Call(), and garbage collection.
...with unprotect
statements.
Within the C code, we manage our own memory using malloc(...) and
free(...). We detect no memory leaks, and our experience has been
that they are relatively easy to detect under stress given the large
memory imprint our data structures typically have. Stack usage using
Cstack_info() is stable.
For clarity, pseudo code for the trivial stress loop is as follows:
formula = as.formula(Survrsf(time,status)~.))
data(veteran, package="randomSurvivalForest")
for (i in 1:1000) {
growObject = rsf.default(formula, veteran)
predictObject = rsf.predict(growObject, vetera...

Stack checking, core dumps, and embedding R
I will say this first -- I can't copy/paste the error message from the
screen, so it's being retyped. Errors might occur. SORRY.
I've been experiencing some interesting stack warnings recently when
moving from R 2.2.x to the R 2.3.0 series and the R 2.4.0 series. In
particular, I'm getting warnings of "Error: C stack usage is too close
to the limit" before

o There is some basic checking for imminent C stack overflow (when
the evaluation depth and the user interrupts are checked).
On systems with suitable OS support (not Windows), segfaults
from C stack overflow are caught and treated as an R error.
New function Cstack_info() reports on stack size and usage.
options(expressions) reverts to the default of 5000 now
stack checking is in place.
