similar to: write.csv causes system() and ? to stop working

Dear R users, I have recently begun to reuse some functions I made several months ago. The scripts write to a .csv file using the 'write.csv' function with the append option set to TRUE. This used to work fine, albeit with the warning "appending column names to file". I upgraded to R version 2.11.0 on OSX 10.5.8 and 'write.csv' will no longer append any files - I get the

Dear R experts, I have been looking into the help-pages and old questions from the R-Help site, but the options offered there don't seem to work in my case. First of all, I am working on Windows XP, using R version 2.6.2. I am attaching two csv files as an example of how the data I am traying to put together is delivered to us. On the first row of every csv file is the name of the

I have a simple command to export a data.frame: write.csv(output, "TotalPredicted2008.dat") The structure of the data.frame can be seen with: > head(output) DayOfYear Sales 1 1 1429 2 2 3952 3 3 3049 4 4 2844 5 5 2219 6 6 2340 But it seems that the index is getting written out to the file. The first few lines look like:

Hello, Is there a way to put multiple data.frames or objects into a single .csv ? I know I can use sink() to do this for a text file. Is there way to do it for a .csv? e.g. for sink() sink("c5.k.s.p.92.LN.sl.vs.mean.txt") symnum(c5.k.92.LN.sl.vs.mean) symnum(c5.s.92.LN.sl.vs.mean) symnum(c5.p.92.LN.sl.vs.mean) sink() Could I put these all into a single .csv, in a similar format to

Hello all, Have a little annoying issue with wreite.csv. It always writes out observation number. Is there a way to avoid this.

Dear R-users, currently I am working with the R version 2.4.1. I realized it has a feature, which might be wonderful (as so many things in R), but in this case might be a bit dangerous as well. It seems that columns of a data frame can be called just by indicating the first letter of the name of the column. For example: first_item <- seq(1,10) second_item <- seq(11,20) dat <-

The write.csv() function is currently implemented as function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=NA, sep=",", qmethod="double") } Surely, it should be function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=col.names, sep=sep,

What OS are you on? On Ubuntu 17.10 with R 3.4.3 all seems well (see below for your example, I just added a setwd()). [ That said, I long held a (apparently minority) view that csv is for all intends and purposes a less-than-ideal format. If you have that much data, you do generally not want to serialize it back and forth as that is slow, and may drop precision. The rds format is great for R
