Hello, For reasons I don't understand, data() imports CSV (Comma-Separated Values) as if they were delimited by semicolons instead of commas. (Are semicolon-separated Comma-Separated-Value files common somewhere?) Given that this is the case, if I choose to put comma-delimited CSV files in my data directory, what is the preferred method of loading these into memory?

I''m trying to generate (and manage) nagios configuration based on what classes have been included by nodes. I''ve seen the example at http://docs.puppetlabs.com/guides/exported_resources.html, and I''m doing that now. However, it has some problems: - puppet runs are very slow on the nagios node - when I want to change the service configuration in nagios, I have to wait

Hey I am pretty new to Ruby on Rails and I have no idea how to solve the following: I have a join query on a table like this: def mytags Taggable.joins("JOIN taggables as filter ON taggables.tag_id = filter.tag_id WHERE filter.taggable_type = ''User'' AND filter.taggable_id = 1").all end this works perfectly fine. then I want to join the result on another

Hi Listers, I can't seem to figure out why I loose precision when I try to import a comma delimited file using read.csv or read.table. The fields of interest are rounded to one decimal place.

Dear list, I have a file that is comma delimited but contains some erroneous non-delimiter commas. I would like to replace these commas with semicolons and then read the correct file into R as a data frame. I want to do this from within R, without changing the original data file. My current idea of how to do this would be to use system("sed ...") and feed the result to read.csv(), but

The main limitation of the shapefiles package that I put together is that it does not create shapefiles from R objects - rather it only writes shapefiles that have been read into R and manipulated within the constraints of the existing file structure. By this I mean that for example you can change the coordinates of points and write them back out. Or you can add a bunch of blank columns in the

Dear all What is the preferred spreadsheet-like x-delimited data format for use with R? Should I prefer tab-, comma-, space- or some_other_delimitor-seprated data? I'm asking this because I've been once bitten by CSV data containing ` ' ' (apostrophe) symbols that R couldn't easily digest. Probably no the best approach, I've eventually inspected the document and removed

I have a list of data that is delimited by a / and, as long as there is an equal number of delimiters, I can parse the data and put it into a data frame: > t1<-c("a/a/a","b/bb/bbb","ccc/cc/c") > t2<-strsplit(t1,"/") > t3<-data.frame(t2) > t3 c..a....a....a.. c..b....bb....bbb.. c..ccc....cc....c.. 1 a

I've created a Perl script that translates Microsoft Excel (.xls) files into comma-delimited text files (.csv) using the Perl Spreadsheet::ParseExcel module.

I am trying to write data to csv but I am having issues with the separations. Basically I have some results that I get with R that I copied and pasted into word and then saved as .txt I want to write the results to csv because it's easier to make tables in word (all I would have to do is copy and paste into a table, instead of typing everything out). I am able to write the data to the

I'm using read.delim to successfully read in tab delimited data, but some columns' values are comma seperated, reflecting the fact that user chose a few answers on a multi-select question. I understand that each answer is its own category and so could be represented as a seperate column in the data set, but I'd like the option of reading in the data column, and converting it to a

Hello, all. I'm having a nasty problem with call parking in Asterisk 1.6.1.1 that smells like a bug. When the call returns, it seems to be returning to a "|" delimited extension and failing. Here is the output from the console: [Jun 26 22:20:42] NOTICE[7168]: chan_sip.c:18160 handle_request_invite: Call from 'tkeeley' to extension '56' rejected because extension

Hi. in the Rails Agile book here''s what was happening: >>> module StoreHelper def hidden_div_if(condition, attributes = {}) if condition attributes["style" ] = "display: none" end attrs = tag_options(attributes.stringify_keys) "<div #{attrs}>" end # format_price method ... end Note that we cheated slightly here. We copied code from the Rails

Hi all,I have large compressed text tab delimited files, I am trying to write efficient function to read them, I am using gzfile() and readLines() zz <- gzfile("exampl.txt.gz", "r") # compressed file system.time(temp1<-readLines(zz )) close(zz) which work fast, and create vector of strings. The problem is to parse the result, if I use strsplit it takes longer

I'm trying to convert a data.frame to a series of strings (row-wise). There was a very good discussion awhile back (2002) entitled "[R] string concatenate across rows of a matrix??" where Tony Plate recommended the following two alternatives (x2 is an R object of type data frame -- a matrix also works for solution #1): 1) apply(format(x2), 1, paste, collapse=" ");
