Hello, I have a following dataframe with many rows. data.frame(match.start=c(5,10,100,200),range.coordinates=c("1000-1050","1500-1555","5000-5050,6000-6180","100-150,200-260,600-900")) match.start range.coordinates 5 1000-1050 10 1500-1555 100 5000-5050,6000-6180 200

Hi Stephen, I am not sure that the "for loop" is the source of slowness. You seem to be doing a lot of unnecessary work each time through the loop. e.g. no need to check if it's the last file, just move that section outside of the loop. It will be executed when the loop finishes. As it is you are calling list.files() each time through the loop which could be slow. In any case

Eric's approach seems reasonable to me, and I agree that it's probably not the use of a "for" loop that makes the original version slow. As Eric mentioned, there are lots of unnecessary things happening in the loop. For example, list.files() was called twice inside the loop, which is unnecessary, and will definitely slow the loop down (though probably not by much). Call it

Forgive me, I'm a novice. Consider that today I have already set up a working postfix + Dovecot server with userdb using the static driver and passdb using a password file (in the format <username>:{hashing algorithm}<password hash>). The Dovecot server has several mailboxes which are already in use today. I understand that I'll need to change over to using the passwd-file

Hi, We have a Ubuntu 14.04 server with dovecot 2.2.9 If I try to run /usr/bin/doveadm search -u email at exmaple.com mailbox Junk savedbefore 30d It will dump a core file. We have a similar config on an other server and there is no problem there. Any ideas how to prevent the core dump? root at triws2:~# gdb --args doveadm search -u email at example.com mailbox Junk savedbefore 30d Reading

Dear All, Suppose I have a dataframe like this with many thousands rows all with different names: data.frame(gene=c("a","b","c","d","c","d","c","f"),value=c(20,300,48,55,9,2,100,200)), I want to set column "gene" as row.names, but there are duplicates (c, d), which I want to transform into this as row names:

Dear All, I have a following for-loop code which is basically intended to read in many excel files (each file has many columns and rows) in a directory and extract the some rows and columns out of each file and then combine them together into a dataframe. I use for loop which can do the work but quite slow. How to make it faster using lapply function ? Thanks in advance! temp.df<-c() #

Dear All, I am new to R. I have a 2 column data frame with more than ten thousand rows. Something like below. I want to add up all duplicated items, e.g. the three "aa" add up together to get a single value gene=a, value=74. How can I do that?? Thanks for help ! gene value aa 20 bb 10 cc 9 aa 30 aa 24 dd 100 ee 55 .... ... Millions thanks. Best Regards, hon WONG, Hon-Kit

I have been going crazy with this also since Sat. Our server was working perfectly with BV but will now not place calls to BV. Incoming from BV works fine. I felt sad rebooting it today, it had been running for almost 200 days! Here is my error message from the console... Notice I am running today's CVS Connected to Asterisk CVS-03/08/05-14:32:39 currently running on com (pid = 1624)

I am using a postfix + Dovecot server as a test mail server for which some applications in our test environment use as a target to deliver email so that our real endusers don't receive messages from our test servers. A few of the mailboxes in Dovecot receive hundreds of emails per day. I'd like to automatically remove all emails in all mailboxes and mailbox folders that were received

Hi all, Paul Anderson, a friend of mine who works at the University of Edinburgh, is looking for complicated problems that are currently difficult to handle with existing config mgmt tools.
