Hello, I've a weired problem with a data frame. Basically it should be just one column with specific names coming from a data file (the file contains 2 rows, one should be the for the rownames of the data frame the other contains numeric values). > df.rr <- read.table("RR_anova.txt", header=T, comment.char="", row.names=1) > df.rr[c(1,2,3),] [1] 1.11e-16 1.11e-16

Hi, I am trying to run PCA on a set of data with dimension 115*300,000. The columns represnt the snps and the row represent the individuals. so this is what i did. #load the data code<-read.table("code.txt", sep='\t', header=F, nrows=300000) # do PCA # pr<-prcomp(code, retx=T, center=T) I am getting the following error message "Error: cannot allocate vector of

Dear all, Trying to test for heteroskedasticity I tried several test from the car package respectively lmtest. Now that they produce rather different results i am somewhat clueless how to deal with it. Here is what I did: 1. I plotted fitted.values vs residuals and somewhat intuitively believe, it isn't really increasing... 2. further I ran the following tests bptest (studentized

Hi all I'm writing a direct llvm backend for gcjx a new java fronted for gcc. I'm now ready to tackle creating the structures to represnt classes I read the gcc 4.0 patches and it seems that the llvm struct is padded and aligned using the info from the gcc tree. In my case I don't have this information. I'm willing to intially let llvm align and pad the struct but its not clear

hello; firstly, my gratitude to all who help me to find a function that allows me to add confidence interval to my graph. in order to calculate the (1-alpha)th percentile of for exemple an F(df1,df2) distribution i do like this: v<-df(alpha,df1,df2) percentile<-qf(v,df1,df2,alpha) if it is true please alert me , and if it is not what should do then? :handshake: -- View this message in

Please, I seek expertise and advice, possibly leads to R packages or stats literature. My data: measurements of economic variables for each county of California over 37 years. My dependent variable is square feet of office floor space permitted to be added in a county. Independent variables include for example change in number of office jobs in same county same year (and lagged years).

Thanks for improving this! Since no good deed can go unpunished, could you also update the LangRef and codegen documents to describe the new state of the world? It might also be nice to mention there that tail calls can be needed for correctness in addition to performance and how users can guarantee that a call will be transformed, since both if us have forgotten recently. I can take a stab at the

Karanbir, No one should ever have to go through that. I am sorry to hear that someone has done that evil deed to you. May they be forgiven, but know the pain that they have caused you and repent of their sins. And if there's something I can do to help, please let me know. ******************************************************************************* Gilbert Sebenste

I have read multipe messages here from people upgrading from 5.0 to 5.1, presumably using "yum update" to do the deed. When I do "yum update" on my (I think) fully updated Centos 5 system I get no updates. Am I just being impatient (i.e., the updates haven't yet been pushed out) or am I somehow missing them?
