...s: A <- c(1:10) B<- seq(1,10,2) Now I want to make a table form vectors A and B as rows, and if a value of A isn't present B, then I want to put a N/A symbol in it: Output should look like this: 1 2 3 4 5 6 7 8 9 10 1 0 3 0 5 0 7 0 9 0 How can I do this in R? Thank you. -- Andris Jankevics Assistant Department of Medicinal Chemistry Latvian Institute of Organic Synthesis Aizkraukles 21, LV-1006, Riga, Latvia

Is there any generic function that gets the "home" directory? This should return /home/<user> in Linux and x:/Documents and Settings/<user> (or whatever) in Windows XP. Another (unrelated) question: what is the _simplest_ way to read and write R variables to/from files such that they are stored in a human-readable but R-like form? For example, if (say), x is a vector

...3,4] (4,5] 4 4 3 5 But how can I find a break points for vector with random values and random number sequence intervals? Why result for interval (1,2) is 4, if there is only 3 values of "1"? Can I get from vector Z a smal vector Zs 1,2,3,4,5 ? Thanks a lot! Andris Jankevics

...possible to have a greek symbols in xtable cells? How can I get for example a string of : $\Delta$ > "$\Delta$" [1] "$Delta$" And string: > "$\\Delta$" [1] "$\\Delta$" Gives a latex aoutput like: \$$\backslash$Delta\$ Thank You in advance Andris Jankevics

Hello useRs, I can't figure out how can I store a data frame of values of X and D from this loop: Z <- c(1:10) for (i in 1:(length(Z)-2)) {D <- x[1:(2+i)]; X <- paste("x",sep="",i) print (X) print (D) } Thank You, Andris Jankevics

I keep getting the 'memory.size' error message when I run a program I have been writing. It always it cannot allocate a vector of a certain size. I believe the error comes in the code fragement below where I have multiple arrays that could be taking up space. Does anyone know a good way around this? w1 <- outer(xk$xk1, data[,x1], function(y,z) abs(z-y)) w2 <- outer(xk$xk2,

Hi, I have some big calculations in R to be done. Since I can use R on a server with ssh, i was wondering if I can reopen a R Shell after exiting ssh. I don't want to use the batch mode and nohup doesn't work. I want to use something like ssh user at server R ---do something in R and start calculation --- close ssh but let R remain on the server, doing the calculation ssh user at

I would like to run a for loop with an index going from 0 to 499 but the following seems to miss out the first value: C <- 499 for (i in 0:C) The alternative is: C <- 500 for (i in 1:C) { #Then every time I use i, I replace it with i-1 } Is this a good way to do it or is tere a better way?

Dear all, I am trying to my dataframe for the PLS analysis using the PLS package. However I have some trouble generating the correct dataframe. The main problem is how to use one name to represent several columns in the dataframe. The example dataframe in PLS package is called "sensory". I cannot directly read the data file since it's a binary file. If I use

Hello, I have a large data matrix (68x13112), each row corresponding to one observation (patients) and each column corresponding to the variables (points within an NMR spectrum). I would like to carry out some kind of clustering on these data to see how many clusters are there. I have tried the function clara() from the package cluster. If I use the matrix as is, I can perform the clara

All, I am working with NIR spectral data and it was great to find that the example in ?plsr also used spectral data. Unfortunately, I am having difficulty figuring out how the "yarn" dataset is structured to allow for the plsr model to read: library(pls) data(yard) yarn.oscorespls <- mvr(density ~ NIR, 6, data = yarn, validation = "CV", method = "oscorespls")

I've been trough the R documentation for about half an hour and it's not clear to me how to do this: I need to format to character a series of integers from 1 to 1000, and I like them to look like "0001" "0002", "0059", "0123" and so on. Padded with zeroes to have four digits. Cheers! Mario. r-help-request at r-project.org wrote: > Send
