Hi All, I'm trying to create labels to plot such that it doesn't show up as scientific notation. So for example how do I get R to show 1e06 as $1,000,000. I was wondering if there was a single function which allows you to do that, the same way that as.Date() allows you to show in date format on a plot.

Hey all, Suppose a=b^2 for starters. I want to be able to create a graph that displays a initially and if i was to click on 'a' to show 'b' on the chart itself. Does anyone know if this is possible in R? Also as an extension (not necessary as yet) to output the above into a 'html' file.

Hi All, I have a date in the format of yymmdd (without any of the backslashes, eg. 100731). How do I convert this into a Rdate and plot it? I don't want the number of days from 1970's showing up as my date (Its the date I require). Thanks, Sachin p.s. sorry about the corporate notice I can't remove it. --- Please consider the environment before printing this email --- Allianz -

Hi All, I've been looking around (maybe not extensively) but I couldn't find any documentation on the list of fonts thats useable with R. Im trying to change the font of the title, seems like mtext is the only way so far, which can actually write on top of each other depending on the lines: plot(1:5,1:5); mtext("Title",side=3,cex=3.5,line=1); mtext("Sub

Hi all, Just following on from a previous thread (for loop). Is there a parallel 'for' loop like matlab (parfor maybe?). I know there was a Nvidia GPU version for blas somewhere. But is there a CPU or a GPU version of the for loop? Thanks, Sachin p.s. sorry about the corporate notice below: cant get rid of it. Don't have other mail client access at the office :( --- Please consider

Hi R, In the following code my x-axis is formatted in month format. Which Im happy with. The y-axis is what I want to re-format with something else. My question is, is it possible just to switch off the xaxis in plot function (see below). If not how do you get the months to show up as FEB-YYYY, MAR-YYYY and so on, so I could fit a label on x-axis. Thanks, Sachin p.s. sorry about corporate

Hi All, I want to have an array/ matrix that looks this x<- 0 0 1 1 1 3 5 4 4 7 -1 8 9 10 6 I hope this makes sense. So basically if I want x[1,3] it will access 0 and similarly x[4,2], -1.

Hi All, Currently my plot shows the y-axis in scientific notation (1e07 and so on). I want to be able to display this in dollars such that it shows $10,000,000 (including the commas). How do I do this. Also with the xlabel and ylabel. I've specified: 'title('Cash vs Time',xlab='Period',ylab=''); Im hoping that this will also not display anything on the y-axis.

Hi All, I've reproduced the example from Prof. Friedrich Leisch's webpage. When I write sweave("Example-1.Snw") OR sweave("Example-1.Rnw"), (yes, I renamed them). I get the following error: Writing to file example-1.tex Processing code chunks ... 1 : echo term verbatim Error: chunk 1 Error in library(ctest) : there is no package called 'ctest' Also while

I stupidly decided to save my last workspace (a large dataset) and every time I open R it loads it back in. Can I stop this? Also how do you clear variables.

Hi All, I am trying to run R scripts on a server rather than my own machine. The biggest reason being that the data can be 3GB+; more than my RAM can handle. Anyway is there a way to do this. I am trying to find a SAS alternative. In SAS you can do (keyword) rsubmit; and get things running remotely on a server. Is there something similar on R. Couldn't find a comprehensive answer online.

Hi All, When I run the following code, I cannot see the entire number. As opposed to seeing 1,000,000,000. I only see 000,000 because the rest is cut off. The cex option doesn't seem to be doing anything at all. y<-seq(1e09,5e09,1e09); plot(1:5,y,ylab='',yaxt='n' ); axis(2, at=y, labels=formatC(y,big.mark=",",format="fg"),las=2,cex=0.1); Any thoughts?

Hi All, Is it possible to write a program such that it downloads a csv from a given web address? Would be great if this could be done at a particular time during the day as well. Say 9AM monday-friday. Incase you are curious Im just trying to analyse some stocks data.

Hi all, When I write out some values and then use 'plot' and 'lines' respectively I can get R to plot me two lines. However when I get the data from a csv file and run it I only manage to get one line running (whichever was invoked first). The sample files are attached below and I've reproduced the code below with the suspicious part marked as #??? (not even sure if thats

Hi all, What would be an efficient way to match rows of a matrix to a vector? ex: m<-matrix(1:9, nrow=3) m [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 ################################# which(m==c(2,5,8)) # I want this to return 2 ###################### Thanks, Sachin [[alternative HTML version deleted]]

I am using a similar dataset to the following: a= c("Fruits", "Adam","errorA", "steve", "errorS", "apples", 17.1,2.22, 3.2,1.1, "oranges", 3.1,2.55, 18.1,3.2 ) a_table=data.matrix(t(matrix(a,nrow=5))) I would like to plus minus every second column starting from errorA (using xtable/ hmisc) example output (ignoring

Hi all, It seems like I cannot use normal 'if' for data frames. What would be the best way to do the following. if data$col1='high' data$col2='H' else if data$col1='Neutral' data$col2='N' else if data$col='low' data$col2='L' else #chuch a warning? Note that col2 was not an existing column and was newly assigned for this

Hi all, I want to do the following: data<-data.frame(col1=c(1,2,3,4,5)) getcol2<-function(data){ data$col2[data$col1<=2]="L" } getcol2(data) Unfortunately in the above col2 does not appear in the final data. So how would you pass this by reference such that you would get it back? Thanks, Sachin [[alternative HTML version deleted]]

Dear R-help list, I am just trying to increase my memory for R, but for some reason I cannot really increase the memory size as much as I would like.
