hi everyone, i am having difficulties with replacing the dates format in R for exporting the data set... eg: the code that i used was toms_dat<- replace(toms_dat, toms_dat ==2009-08-06, 2) toms_dat<- replace(toms_dat, toms_dat ==2009-08-04, 1) but when i export the data as into txt file or excel file the dates come up with very large numbers .....:drunk: please help me ...=) -- View

i was trying to do a for loop for plotting the histograms , but it doesnt work properly > library(lattice) > columns <- 8:153 > plots <- vector("list", length(columns)) > j <- 0 > for (i in columns) + { + plots[[ j <- j+1 ]] <- histogram( ~ data[,i] | data[,2],ylab = "Frequency", + xlab = "Score", xlim = c(1,5), ylim =

I am trying to reshape data that are in the wide format into the long format. The design is a repeated-measures design, which combined 3 levels of shape (circle, square, triangle) with 3 levels of color (Blue, Red, Green), for a total of 9 variables. The wide data look like this (sorry I couldn't get the columns to line up quite right: Subject CircleBlue CircleRed CircleGreen SquareBlue

If it's the latter, I sugguest you find scientific or graphic applications. I don't think there is auto-parallelization benchmark, however. Regards, chenwj -- Wei-Ren Chen (陳韋任) Computer

Hi Changcheng, The question you ask seems to be a different topic from this thread. If possible, I sugguest you lauch another thread so that people know what you want to ask by looking at subject. Since you're working on C backend, you may want to collaborate with Roel, who is working on C backend, too [1]. Regards, chenwj [1]

Hello All, I'm having some trouble reshaping my data from wide to long format. I have tried using both the reshape function and package. Although I haven't worked much with the reshape function, I have found the reshape package useful and intuitive for reshaping data from long to wide format. However, going the other way has me stumped with this type of data. My data is set up, roughly,

Hi all, I have been struggling with this problem for a few days. I have a data table like this: gene rpkm1 diff1 rpkm2 diff2 gene1 23 50 13 120 gene2 111 220 827 1200 gene3 75 998 71 910 And I want to re-format it so that, for each gene, I have a 2x2 contingency table, such as: gene rpkm diff gene1 23 50 gene1 13 120 gene2 111 220 gene2 827

The problem is that I could not write any Hebrew character... Whenever I type a character I get "?". So I've looked at wine-bidi issues, and found that I need to compile wine with icu library. I did! using

I must install MS Office in Wine on Ubuntu Linux. It installs fine, but the Hebrew is backwards. Googling the problem led me to this video, which illustrates the problem: http://www.youtube.com/watch?v=19I2qaykE6w Does anyone know how to fix this? I am on a full UTF-8 Hebrew locale, if that is relevant. I installed MS Office 2003 in English on Kubuntu 8.04. Thanks in advance. $ wine --version
