Hi R users, I am new to R and am trying to merge data frames in the following way. Suppose I have n data frames each with two fields. Field 1 is common among data frames but may have different entries. Field 2 is different. Data frame 1: Src Target1 1 aaa 1 bbb 1 ccc 2 aaa 3 ddd Data frame 2: Src Target2 2 aaaa 3 dddd 4 bbbb 4

I have a value a=300 observation (x) = sample(1:50) How to find a p-value from this. I need to show that "a" is different fom mean(x). Thanks -- ------------- Mary Kindall Yorktown Heights, NY USA [[alternative HTML version deleted]]

I installed some downloaded packages in R. I always do $sudo R CMD INSTALL <anRpackage.tar.gz> By default it is storing these packages into my directory /home/mary/R/x86_64-pc-linux-gnu-library/2.13/. However I want them to be systemwide into /usr/local/lib/R/site-library/ folder. I tried $sudo R R> install.packages("anRpackage", dep=TRUE) I did not succeed into getting

Hi R users, I try to read a data file (tab delimited format) in which some of the entries in a particular field are missing.

I am downloading say 100 files from ucsc website and storing it into dest folder. download.file function create a file in destination folder even if the file is not present which is something I dont want. So I wrote if condition to remove the file if the download function has non zero value. Now it exits when there is an error or file not present. How can I use "try" and "if"

I have two one dimensional list of elements and want to perform cbind and then write into a file. The number of entries are more than a million in both lists. R is taking a lot of time performing this operation. Is there any alternate way to perform cbind? x = table1[1:1000000,1] y = table2[1:1000000,5] z = cbind(x,y) //hanging the machine write.table(z,'out.txt) -- -------------

Hi Thanks Gabor for your suggestion. I am posting the code that worked for me. dataframe1 = data.frame(cbind(Src = c(1,1,1,2,3), Target1 = c('aaa','bbb','ccc','aaa','ddd'))); #must be data frame dataframe2 = data.frame(cbind(Src = c(2,3,4,4,4), Target2 = c('aaaa','dddd','bbbb','eeee','ffff'))); dataframe3 =
