Error in question ("Error: segfault from C stack overflow")
appears to be associated with long "date" vectors, and is
addressed in the R project's PR #14267, incorporated in R
2.11.1, announcement of the release of which may be found at
dated 2010-05-31 09:16:36 GMT.
I was running R 2.11.0_1.
It is believed that upgrading the port to R 2.11.1 will
resolve this error.
How-To-Repeat: Ensure the existence of a suitable file to read; the one I use
in the following example (/tmp/individual_allocations) has
> I <- read.table("/tmp/individual_allocations", header = TRUE, colClasses = c("Date", "numeric", "numeric", "numeric", "numeric"))
> png("/tmp/Space_Date.png", width = 700, height = 700)
> Is <- subset(I, as.numeric(I$Tag) %% 7 == 6)
> xlist <- as.numeric(unique(Is$Tag)) - as.numeric(min(Is$Tag))
> boxplot( GB_total ~ Tag, data = Is, varwidth = TRUE, notch = TRUE, col = "lightblue", medcol = "darkblue", xlab = "Date", ylab = "Allocation size (GB)", main = "Local Disk Space Allocation Distributions by Date", at = (xlist/7), xlim = c(0, max(xlist/7 )))

and rebuilding math/R, using the just-built R 2.11.1 did, in fact, avoid
the "Error: segfault from C stack overflow" condition; I was able to
create all of the plots without incident.
There may be other issues with 2.11.1, or there may be issues with
environments other than FreeBSD/i386 stable/7; I have not tested that.
But the above patch does appear to be sufficient to update the port from
2.11.0_1 to 2.11.1, and the resulting executable and associated
libraries appear to work.

I had meant to update the port earlier, when the bugfix release first
came out, but I was preoccupied by some other matters. I will try to
submit an update soon. I am glad that you find it useful, and I am
sorry that you have been -- er -- bugged by the problem with the
