Hello R helpers, I would like to automate this code for many files of the same type. But I don´t know how to make it. In particular, i don´t know how to read many files each one as an r object with the name of the file. Then a for loop would be sufficient, right? Many thanks and a happy new year.

I'm trying to declare a few date-related global variables to ease my dialplan. When I declare the following in the [globals] context of extensions.conf, I get unexpected results: YEAR = ${STRFTIME(${EPOCH},,%Y)} MONTH = ${STRFTIME(${EPOCH},,%m)} DAY = ${STRFTIME(${EPOCH},,%d)} TIMESTAMP = ${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)} If I evaluate these variables in the dialplan later, using exten

Hi, In voicemail.conf, you can read ; Look in /usr/share/zoneinfo/ for names of timezones. ; Look at the manual page for strftime for a quick tutorial on how the ; variable substitution is done on the values below.

R 2.6.1 on a Thinkpad T60 running up-to-date Gentoo: Despite the documentation, which says: 'strftime' is an alias for 'format.POSIXlt', and 'format.POSIXct' first converts to class '"POSIXlt"' by calling 'as.POSIXlt'. Note that only that conversion depends on the time zone. strftime fails on POSIXct objects: > foo <-

Hello! I've been trying to get this right for quite a while now and fear there is an easy solution I just don't see. I did not have this problem in Linux, and I searched r-help and Google but did not find a solution, but of course I am grateful for and resources I might not have found our not understood yet. I try to parse a time stamp with time zone. I essentially just want to parse the

How get i only the merge of cells with a number? datos$NEW <- do.call(paste, c(datos[,19:53], sep = ";")) $ NEW : chr

Hi I have many excel files were the Date field was not declared as date, so the dates look like this: 1/2/1978 I know that the format is day/month/year How can I make R change this to Date format?

Hi, I''m calling a helper I''ve written - format_time() that is called from my views with a given time that was selected from my database and was returned to the view via an instance variable. When I call format_time from a partial, I see that I get some kind of String error and the partial won''t render. Basically, the object being passed in to format_time is already a

Dear developpers, I successfully compiled OpenSSH 2.9p1 which I get via CVS with a little modification. Patch is available at http://www.rc.tutrp.tut.ac.jp/~nakaji/install/NEWS/utils/ref/openssh_cvs-news4.diff.gz But one problem remains. In config.h.in, there is a definition about strftime function /* Define if you have the `strftime' function. */ #undef HAVE_STRFTIME but this
