similar to: Read text file subsetting rows

Hi R folks, Can anyone tell me how to read in a pipe ("|") delimited text file? I've tried the following: read.delim("c:/junk/junk.txt",sep="|", skip=7, check.names=FALSE,quote = "", header=F) The file looks something like the following: RD|I|04|013|9997|68103|5|7|017|830|20000221|00:00|12.6||6|||||||||||||

All, I have a 30 million record text file without header information. I would like to add a header to this file without reading it first. Is this possible? The code below does what I want except that the readLines portion takes quite a long time. Is there a way around reading the lines? I'm working on Windows XP. Zev input<-readLines("c:/junk/forR.csv")

Hi R folks (Dr. Bates in particular), In August 2005, Dr. Bates mentioned that the documentation for lme4 "will be in the form of a book with the working title 'Multilevel Modeling in R'" and I'm just wondering if there is an estimated date of publication or if it's still a long way off. The Rnews article does a great job of introducing the package, but I'm

Hi, For some reason I'm finding that my table caption is disappearing if I print xtable output with the floating argument set to FALSE. Below is a very simple Sweave file that produces two tables the first has no caption and the second has a caption (if you want to see it http://www.zevross.com/temp/test.pdf). Does anyone know what I can do to fix this? Zev (I'm using Windows 7, 64

Hi All, Is there a simple way to convert a string such as c("A", "B" ,"C", "D") to a string of c("Group1", "Group1", "Group2", "Group2"). Naturally I could use the factor function as below but I don't like seeing that warning message (and I don't want to turn off warning messages). Perhaps a function

Hi, I had my R to MySQL 5.0 connection working fine under 2.5.1 on Windows XP. My MySQL installation is local, not on a server and I could connect with: con <- dbConnect(MySQL(), dbname = "mydatabase", user="root", password="XX") I have updated to R 2.8.1 (RMySQL 0.7-2) but that same line of code yields: Error in mysqlNewConnection(drv, ...) : RS-DBI driver:

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.   One function that has me stumped is "sink." Can anyone tell me if this stands for something?   Thanks,   Paul         __________________________________________________ [[alternative HTML

Let me start by saying I am rather new to R and generally consider myself to be a novice programmer...so don't assume I know what I'm doing :) I have a large matrix, approximately 300,000 x 14. It's essentially a 20-year dataset of 15-minute data. However, I only need the rows where the column I've named REC.TYPE contains the string "SAO " or "FL-15". My

I tried to recreate this by installing void x64_64 to a VM, but couldn't - the test passes for me.a My system ended up with a slightly newer kernel (4.17 IIRC).

I would like to read the following hierarchical data set. There is a family record followed by one or more personal records. If col. 7 is "1" it is a family record. If it is "2" it is a personal record. The family record is formatted as follows: col. 1-5 family id col. 7 "1" col. 9 dwelling type code The personal record is formatted as follows: col.

Hello all, I recently found myself wanting to run sshd with passphrase-protected host keys rather than the usual unencrypted format, and was somewhat surprised to discover that sshd did not support this. I'm not sure if there's any particular reason for that, but I've developed the below patch (relative to current CVS at time of writing) that implements this. It prompts for the
