similar to: Problem with a regular expression.

I tried this on a Linux (Ubuntu) server invoking R from the command line and the result was the same, except that I could kill the R session from another terminal window.

The issue seems related to R bug report 15012: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=15012 As mentioned in the comments there, a pull request to the TRE library has recently been made, but I don't know about its status.

The problem is in TRE library, in regcomp, while compiling the regular expression.

Hello, This seems to be serious. RGui.exe, fresh session. I've clicked File > New Script and wrote Oldterm <- c("A", "B", "A", "*", "B") strsplit(Oldterm, "\\\\)" ) Ran each instruction at a time with Ctrl+r and with the strsplit call the system froze. Ctrl+Alt+Del didn't work, I had to go for the power switch button.

If no 'type' is specified, download.packages("pkgname") will download source packages (.tar.gz files), even on Windows. However, the help says type character string, indicate which type of packages: see install.packages. and on Windows, install.packages defaults to downloading binary packages. Is this intended behaviour on the part of download.packages? This is on R

Hello, I'm having some trouble trying to set the .libPaths() on Windows 7, R-2.15.0 and R-2.15.1. The environment variables R_LIBS and R_LIBS_USER are set according to the help page for .libPaths() and the Rprofile.site file has the default setting, as shown below. R-2.14.1 recognizes the lib paths but not R-2.15. Is this a bug or am I doing something wrong? (I've also tried with

Hi, I want to reporte some strange behaviour with the "months" function, from base R. When using "months" to extract months from a date column, I'm getting the months in english, when I was expecting months in spanish. When using "weekdays" to extract days of week from a date column, I'm getting the the days in spanish (as expected). My understanding is

For what it's worth, I tried setting my Region | Formats setting to Spanish (Peru) in Windows 10 Control Panel, and got Spanish weekday and month results. I believe on Windows we use the Microsoft C strftime function to produce these strings, with the %A (for weekday) or %B (for month) formats. So this question probably needs to be addressed to Microsoft. Duncan Murdoch On 05/06/2017

Dear all, Is there a good way of doing the following conversion: [YYYY]-[MM]-[DD] [Time] [Day] [Name][Integer].[Extention] to become C:\test\[Name]\[YYYY]-[MM]-[DD] [Time] [Day]\[YYYY]-[MM]-[DD] [Time] [Day] [Name][Integer].[Extention] i.e. these 2009-04-10 1400 Fri Foo1.txt 2009-04-10 1400 Fri Universities2.txt 2009-04-10 1400 Fri Hitchhikers Guide To The Galaxy42.txt will become

can someone show me how to use a regular expression to break the string at the bottom up into its three components : (-0.791,-0.263] (-38,-1.24] (0.96,2.43] I tried to use strplit because of my regexpitis ( it's not curable. i've been to many doctors all over NYC. they tell me there's no cure ) but it doesn't work because there also dots inside the brackets. Thanks.

Dears Sirs During my computational work I encountered unexpected behaviour when calling "ar" function. I want to select the order p of the autoregressive approximation by AIC criterion and sometimes an error occurs. Example: # time series

Hi, Is there a way in R to get the string which matches the expression, where the expression is a substring of the parent string. Lets say, I have $i <- "transcript:ENST0000112334 pid:ENSP000012345" What I need is the string "pid:ENSP000012345" from $i using the query "ENSP". Appreciate your comments.
