Previously I had problems with data(foo) and Gass and I had problems with help(). His diagnostic was "POSIX regular expressions not available" and mine was "invalid regular expression". Martin Maechler has no problems with Solaris 2.5 and suggested a regular expression library was needed, e.g., regex-x.xx. Solaris 2.4 has regex.o in /usr/ccs/libgen.a and regex.h in

Dear R-help subscribers Would you tell me how to apply SSfpl with binary data as below? Unfortunately, there is not the EXAMPLE in help(SSfpl) for binary data but for quantitative data(Chick).

Dear R-users I would like to apply classification and regression tree(CART) to the following data. I have some question on using 'tree' package. The data contains one response variable Y and five explanatory variables. The explanatory variable "x2" is categorical and not ordinal. But, the result obtained after running following R code has indicated that x2 is regard as

Hi, this is not a bug report since this may not be a problem with R per se. The current release of R (1.1.0) will compile cleanly on an AIX box (I have 4.3.2) but it will fail upon startup with an Illegal Instruction. I've located the problem to be in do_strsplit when R calls regcomp. This function is defined in regex.c. However, the text from regex.o doesn't find its way into the

If cmake happens to detect GCC for the C compiler and Clang for the C++ compiler, then a manual override of either the C compiler or SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG is required. This has been happening on my Darwin build environments: -- The C compiler identification is GNU 4.2.1 -- The CXX compiler identification is Clang 4.1.0 Without the manual overrides, all C sources fail to compile

Dear R-lists I have just upgraded the version 1.5.1 from 1.4.1 in my laptop PC, because, I have to prepare graphs by using the grid and lattice packages. I tried it with 1.4.1, but I could not it. After upgrade to 1.5.1, I have finished it. Next, I tried to modify some graphs with as follows: # # setting color for graph # library(grid) library(lattice) background <- trellis.par.get()

Hi All, I have two small things that I would appreciate some help with: 1. Config/Alloca.h is now dead. Once configure and cmake support is removed, we can zap it. Can someone remove the cmake/autoconf stuff that pokes at Config/Alloca.h? 2. Daniel's regex email. I think the right answer is to just autodetect whether regcomp/regexec etc are available (his #2). Could someone add

Hey Guys, I'm trying to install R on an SGI IRIX 5.3 machine. I'm having trouble getting R to use POSIX regular expressions. Here is the error message I get when I run help: > help() Error in gsub(pattern, replacement, x, ignore.case, extended) : POSIX regular expressions not available I looked through the R-help archives and I found a few tips concerning the problem. I tried them

Hello, I'm trying to determine if a string contains asterisks using the grep function. I know that this is slightly difficult because * is a special character in regular expressions and needs to be escaped. However, escaping the * using \ doesn't work either: if(grep("\*", model)>0) #does the model have an interaction { do something... } produces the following error

We would like to have access to some kind of regular expression library inside LLVM. For example, we need this to extend the FileCheck test case checking tool to support regular expressions. There are three obvious options: 1. Roll our own library. Multiple unnamed individuals may even already have implementations lying around! :) 2. Use POSIX regcomp facilities. This implies importing some

I am new to R. Just installed it on an SGI running IRIX5.3. The install seemed to go fine. Some basic commands worked as did the demo(). However, I get the following when trying to run help at the command line in R. > help() Error in gsub(pattern, replacement, x, ignore.case, extended) : POSIX regular expressions not available > My best guess is that configure was unable to find
