Hi there, i´ve got a problem with how to create a vector with three variables out of three seperate ascii files. These three ascii files contain pixel information of the same image but different bands and i need a matrix of vectors, with each vector containing the corresponding pixel values for each band. Up to now i´ve seperately read out the ascii files into t...

Hi All, I am working on some ordinal logistic regresssions using LRM in the Design package. My response variable has three categories (1,2,3) and after using the creating my model and using a call to predict some values and I wanted to use a simple .5 cut-off to classify my probabilities into the categories. I had two questions: a) first, I am having trouble directly accessing the probabilities which may have mo...

Dear All,   Here's my problem. I have two lists:   > v [[1]] [1] "five" [[2]] [1] "four" [[3]] [1] "three" [[4]] [1] "two" [[5]] [1] "one" [[6]] [1] "six" [[7]] [1] "five"  "four"  "three" "two"   "one"   "six"  [[8]] [1] "four"  "three" "two"   "one"   "six"...

Dear R experts: I have following data structure: student id, exam time and score. I want to create three new columes: 1 st before, 2nd before and 3rd before. For example, for student 1's 4th exam score is assumed to be influenced by his previous three cloest scores, which are 6, 9, and 10 in that order. For student 2's 5th exam score is assumed to be inflenced by her previous cloest three sco...

I am wondering if there is any function in R that is similar to the "scan" function in SAS. I have a data.frame which has two columns as the following: one two 1 2 3 4 5 6 I used the "paste" function to create the third column: three <- paste(one,'-',two,sep="") so the data.frame is like this now: one two three 1 2 1-2 3 4 3-4 5 6 5-6 My question is, is there any function in R that can do the opposite thing to what "paste" does? suppose I only have the third c...

Hi all, I'm trying to combine exhaustively several character arrays in R like: x=c("one","two","three") y=c("yellow","blue","green") z=c("apple","cheese") in order to get concatenation of x[1] y[1] z[1] ("one yellow apple") x[1] y[1] z[2] ("one yellow cheese") x[1] y[2] z[1]("one blue apple") ... x[length(x)] y...

Hi, I am a new user of R. I have 2 series of nominal data (2 series of answers for the same question) and I want to calculate the correlation between these 2 series. I've tried to use the correlation function (corr, ...) but all are for numeric data... Does anyone know what function should I use for the nominal data? Thanks a lot, Bianca

Should there be a [[<-.factor() that either throws an error or acts like [<-.factor() to avoid making an illegal object of class factor? > z <- factor(c("Two","Two","Three"), levels=c("One","Two","Three")) > z [1] Two Two Three Levels: One Two Three > str(z) Factor w/ 3 levels "One","Two","Three": 2 2 3 > z[[2]] <- "One" > str(z) # the .Data part is now charac...

...first "ifelse" statement successfully does what I want. However, now I want anything less than -4.5 to be green and the rest black. I want another "col" argument but can only use one. How could I go about getting separate colors for anything above 4.5 and less than -4.5? plot(three, type="h", col=ifelse(three > 4.5, "red", "black"), xlim=c(0,500), ylim=range(three), lwd=2, xlab="Chromosome", ylab="Z-Score", font.lab=2, font=2, main="Upregulated Genes in Patient Sample") Thanks in advance, Patrick The info...

say i have a column of data like this... 2 3 4 2 1 6 6 4 7 and i want it in three columns like this 226 314 467 ...so i can make a contour plot.

I tried sorting the search results in Ferret::Index::Index#search and what I found was that the sort is applied not to the whole search but to the returned results. Suppose I have these results: Text - Num foo - 2 bar - 3 far - 4 boo - 1 If I limit the search to the first two and sort by num I get: foo - 2 bar - 3 while I think the natural behaviour would be: boo - 1 foo - 2 Is this

Hi, folks, I'm building a new box, and I want three partitions - /boot, /, and swap, on *one* RAID 1, not three separate partitions. Other than <alt-f2> mdadm..., *is* there any way in the graphical installer to do this? All I see is a way to make three separate partitions. Pointers to links happily accepted. mark, back to googling

Hi everybody, we have three MGE UPS'. I've read all the documents I've found, but I haven't got the information I need. All three of them being attached to the same machine I need a way to identify which is wich (all three use the same driver). They power different systems (two of them running windows so that...

hello, I want to iterate through a list of names and use each element as an argument in a function. For instance: > a = c('one','two','three') > data= c() > for(elem in a){data=cbind(elem = 2,data)} > data elem elem elem [1,] 2 2 2 instead I want 'elem' to be substituted by the string in the list. Doing it by hand would be: > data = cbind('one'=2,data) > data = cbind('two'=2,data...

Hello, I have a basic problem but i can't figure it out with the table underneath. I would like to compute monthly averages. I would like to have the average measure for month #5 for the first three rows (the same number in the first three lines) and the average measure for month #6 for the last four rows ((the same number in the first three lines) in a separate vesctor (let's call it 'result') I tried to use a "while" statement inside a "for" loop but it doe...

Adam: Thanks for putting up this page. But something is wrong. In particular, our Powerware 9135 is a three phase UPS system with THREE 480 volt outputs. So the displayed voltage is not correct -- in fact there should really be THREE voltages displayed, all around 480v. Nut developers: I am copying the NUT mailing list to see if anyone can suggest how to fix this. NUT developers, see the following...

Where data neame=sala.glmm which contain y is response wsf is fixed effect wsm is fixed effects randf is random effect random is random effect The data contain three experiments at the same time. The previous cod is work but it does not give me accurate result especially for the random effects. For experiment I wrote this code experiment <- factor(c(rep(1,120),rep(2,120),rep(3,120))) because I have three experiments at the same time, but if I change the...
