Hi there,
I'm running the Mac OS X version 10.7.5, Processor 2.8 Ghz Intel Core i7,
Memory 4GB 1333 MHz DDR3, and the software is up to date. I get R 2.15.2
GUI 1.53 Leopard build 64-bit (6335), up to date too. Nevertheless I get a
strange error when I try to use the R function plotMeans() in the package
Rcmdr. More precisely, I digit the string 'plotMeans' in the R console, but
when I add the parenthesis '(' I obtain what follows:
*** caught segfault ***
address 0x1000080, cause 'memory not mapped'
Traceback:
1: sys.parent()
2: sys.function(sys.parent())
3: formals(sys.function(sys.parent()))
4: match.arg(encoding)
5: match(match.arg(encoding), c("", "bytes", "UTF-8"))
6: textConnection("rval", "w", local = TRUE)
7: capture.output(print(args(plotMeans)))
8: paste(capture.output(print(args(plotMeans))), collapse = "")
9: gsub("\\s+", " ", paste(capture.output(print(args(plotMeans))),
collapse = ""))
10: doTryCatch(return(expr), name, parentenv, handler)
11: tryCatchOne(expr, names, parentenv, handlers[[1L]])
12: tryCatchList(expr, classes, parentenv, handlers)
13: tryCatch(expr, error = function(e) { call <- conditionCall(e) if
(!is.null(call)) { if (identical(call[[1L]], quote(doTryCatch)))
call <- sys.call(-4L) dcall <- deparse(call)[1L]
prefix <- paste("Error in", dcall, ": ") LONG <- 75L msg <-
conditionMessage(e) sm <- strsplit(msg, "\n")[[1L]] w <- 14L
+ nchar(dcall, type = "w") + nchar(sm[1L], type = "w") if (is.na(w))
w <- 14L + nchar(dcall, type = "b") + nchar(sm[1L],
type = "b") if (w > LONG) prefix <- paste0(prefix,
"\n ") } else prefix <- "Error : " msg <- paste0(prefix,
conditionMessage(e), "\n") .Internal(seterrmessage(msg[1L])) if
(!silent && identical(getOption("show.error.messages"), TRUE)) {
cat(msg, file = stderr()) .Internal(printDeferredWarnings())
} invisible(structure(msg, class = "try-error", condition = e))})
14: try(gsub("\\s+", " ", paste(capture.output(print(args(plotMeans))),
collapse = "")), silent = TRUE)
Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
> plotMeans()
Selection:
What is this? I tried to write the complete string
'plotMeans(dependent_var,independent_var)' and then to paste it in the R
console, but never changes: I obtain the same error, only with a random
different address (see the second line of the error). I also tried to
uninstall the package Rcmdr and then to reinstall it, but again never
changed.
I'm not skilled with computer and software issues, I only argued that this
involves the segmentation of the memory, but I know nothing about this
technical informatics topics. I don't know how to do. I tried to search
some online solutions through forums, but I didn't find any help other than
"check your software is up to date" or "try to uninstall and then reinstall
your R". If possible, I would prefer some 'constructive' solution as I get
R for a long time, and uninstalling it I will loose all the packages I
installed in time.
Thank you in advance for any help or suggestion,
Vanni Rovera
