Hi all! The following code (executed in console)... somevar <- data.frame(v1 = 1:5, somestring = 6:10, v3 = 11:15, v4 = 16:20); somevar %>% gather(key = var, value = val, which(names(somevar) == "somestring"):length(somevar)) %>% head(2); throws... Error in which(names(somevar) == "somestring") : could not find function "which" if I change

rsync does not sync the timestamp on symlink (Solaris 8). It is probablly due to the limitation of Unix implementation of symlink, but I would like to know why rsync/Unix does not do this, and what we can do about it. Is the conclusion that "rsync syncs everything except the timestamp on symlink"? Why do I need timestamp on symlink? Supposed something stopped working because something

hi, I am just playing a bit with the dovecot SASL plugin for postfix and so far my tests have been very successfull, can't wait to get the cyrus-sasl beast replaced. However, I found a potential problem when doing some "illegal" stuff on the postfix side: -------CUT------- cerberus:/var/log# telnet smtptest 25 Trying 192.168.99.99... Connected to smtptest.bestsolution.at. Escape

This is really bugging me no matter what I''m trying. In javascript, I''m using the ajax.updater, and it (obviously) writes back out to a div. I want to then compare what was echoed out into this div (which came from the php file I listed in ajax.updater) with a string. test should equal "SomeString" because that is what is being echoed out to

Hi Guys, I''m having serious troubles resizing a dialog with a ListCtrl. The ctrl will not resize horizontally no matter what I''m doing. I''ve attached a sample code below. Any help will be greatly appreciated, as I really like wxRuby :) I''ve also tried to copy from the example from listtest.rbw, but that also doesn''t seem to work. Another thing

I am calling a bash script and passing in somestring that includes a "$" myscript "$plusmore" I want to assign in the myscript the $1 arg to something like MYTEXT="$1" when I do that I dont get what I'm expecting. if I do MYTEXT='$1' I still dont get what I'm expecting. On the first assignment of MYTEXT I do not want the "$" to be

Hi - I think the patent monster has struck again. rmd = hashlib.new('ripemd160',binascii.unhexlify(someString)).hexdigest() That fails - ValueError: unsupported hash type From some googling, it appears that the supported hash types are from OpenSSL and that means the OpenSSL in CentOS doesn't support ripemd160. I've worked around other stuff missing from CentOS OpenSSL by

Hello, we have 80 text files with matrices. Each matrix represents a map (rows for latitude and columns for longitude), the 80 maps represent steps in time. In addition, we have a vector x of length 80. We would like to compute a regression between matrices (response through time) and x and create maps representing coefficients, r2 etc. Problem: the 80 matrices are of the size 4000 x 3500 and we

Hi, I'm using read.table in a loop, to read in multiple files. The problem is that when a file is missing there is an error message and the loop is broken; what I'd like to do is to test for the error and simply do "next" instead of breaking the loop. Anybody knows how to do that? Example: filelist <- c("file1.txt", "file2.txt",

Hi, I've noticed every time someone does an rsync-request on my ftp-site (which also provides rsync as mirror method), rsyncd creates a filelist. This is a quite IO and CPU intensive procedure, especially for things mirrors like FreeBSD with lots of little files. I was wondering... is there a way to cache that filelist? Our mirrors are updated once, or twice a day, it could speed up

Hi All, I have a slight issue getting R to plot a series of tables automatically. Essentially I have a series of tables that I wish to plot. They are named on_2, on_3 etc. based on the file name when they were read in. I have filelist <- list.files() to give me list of the table names. I wish to plot each table, so I was thinking along some kind of for loop as below: for (i in 1:Number_Files)

Dear all, I am trying to read in and assign data from 50 tables in an automated fashion. I have the following code, which I created with the help of textbooks and the internet, but it only seems to read in the final data file over and over again. For example, when I type:> table_1951 I get the same values in the table as when I type> table_2000 despite the values in the source tables

Dear all, I think I'm nearly there in writing R code which will read in files with two variable parts to the file name and then assigning these file names to objects, which also have two variable parts. I have got the code running without encountering errors, however, I receive 50+ of the same warnings: 1: In assign(paste("Fekete_", index$year, index$month, sep = ""),

After more than one hour of countless tries, I ask myself a simple question : On what items are plugins supposed to execute ? I''ve tried to create a filelist plugin which, for a page, displays all file in the same directory (a rather old school view of website, where each directory contains an entry point). But, whatever I try, my plugin code is never invoked, and my page content is never

I''m still trying to work into Ruby 1.9.2 and am now experiencing something that makes no sense to me. Using rspec 1.3.2 and rspec-rails 1.3.4 with rails 2.3.11 on ruby 1.9.2-p180, when I $ rake spec:models they all pass. When I $ rake spec:controllers they all pass. When I $ rake spec:views they all pass. But when I $ rake spec I get <path to

Hi, As a gentoo-user i frequently run the emerge sync command, which in turn does a rsync with the mainserver. The 'problem' is that the portage directory tree contains about 19.000 directories and 96.000 files. So building the filelist takes a pretty long time, because of the many disk accesses that are neccesary. On the server side the disk-io problem is probably less worse since

okay it appears there are no suspect patent issues with ripemd160 so either they just didn't include it for some other reason or the issue is elsewhere.
