similar to: modifying patterns in a matrix

Dear R-users, I have some nonstandard data set which I would like to plot but don't know how to do it in R. The data is in a matrix where the rows represent samples and the columns represent locations. The entries of the matrix are 0's and 1's, where 1 represents an event and 0 represents a non-event. e.g. aberrations <- matrix(rbinom(1000, 1, 0.8), nrow=20, ncol=50,

Hi, I have an object from the prediction function from the ROCR package and I would like to extract one of the slots from the object, for example the cutoffs slot. However the usual techniques ($, [["name"]]) of subsetting don't work. How can I assess the lists in the slots? Here is an example of what I am working with: library(ROCR) data(ROCR.simple) pred <-

I have a huge dataset for which I only want to read in a subset of it. Is it possible to use read.table to read in only a subset of the data? For example, something like read.table('~/data.txt', subset = chromosome=='1' ) If not, then why not? This seems to be a feature available in all other statistical software. Thanks, Stacey

I have a data.frame, data, with 30 factor variables. I would like to tabulate the frequencies of each variable and output to a tex file using Sweave. Here is my code chunk: <<label=tab, echo=FALSE, results=tex>>= library(xtable) for(j in 1:30){   cap <- paste("Frequency counts for Q",j,".", sep="")   xtable(t(table(data[,j])),caption=cap) } @

Hello - I am a fairly new user of R. I currently have R1.7 installed. I tried to install the KernSmooth package but a message tells me I need R1.8. Is there a way to update to R1.8 while in R1.7 in the same manner that I can use "update.packages", or do I have to install R1.8 in a separate directory and re-install the many packages I have already installed in R1.7? Thanks in advance for

I'd like to remove duplicated rows within a matrix, with missing data being treated as wildcards. For example > x <- matrix((1:3), 5, 3) > x[4,2] = NA > x[3,3] = NA > x [,1] [,2] [,3] [1,] 1 3 2 [2,] 2 1 3 [3,] 3 2 NA [4,] 1 NA 2 [5,] 2 1 3 I would like to obtain [,1] [,2] [,3] [1,] 1 3 2 [2,] 2 1 3

I'm trying to write a function that takes a vector of length n and then takes the first value of the vector i.e j=1 and forms a new vector of length n (i.e replicate the first value n times). This function will then calculate the absoulte difference of the original vector and the new vector and store the results omitting the difference between the value and itself. This function should

HI All, I?m new to Asterisk and also to Linux. I have a large IVR project that I?m about to embark on. I?m new to programming; new to Linux and new to Asterisk. I think I?m about to climb a steep learning curve. I have an existing IVR which is getting on for nine years old and is no longer supported by my vendor. I intend to replicate the system almost as is and then add additional

Hello, I am getting output from anova() and summary(aov()) that depends on the order of the factors in the fitted model object, and this has me baffled. I see this dependency with the data.frame below but not with an example (table 6.4) from Montgomery's DOE book. This is with R 1.3.0 on Debian GNU-Linux.

Hi, Is the rsync-minimalist still supported for windows? I am using Windows XP Home. I am testing, to get a solution for a client. The minimalist looked very nice--a cygwin.dll and an rsync and an ssh.exe. However, I can connect with ssh, but not with rsync over ssh using these files. I have also tried plink from putty with this rsync. I gather from a lot of the messages that the consenus is

All, I am an Splus user trying to use R for a specific project where the client needs the programs to be run in R. Before the holidays, I figured out how to run an R file from the dos command line--it worked great! The command is "Rterm something filename". I can't remember what it is now, and it is driving me nuts. Anyone know? I know I'll feel pretty stupid once the answer

I have setup my Samba server as a WINS server using the wins support = yes parameter. My remote network can see the Samba server at our head office fine. I have also setup the WINS setting on my PC (W2K Pro box) to point to the IP address of my Samba server. When I do a nmblookup -R -U <IP address of WINS server> <name of my PC> on my Samba server I get this reponse; querying pc1

Dear All, I've seen the PRINTER_DRIVER.txt doc on getting the PRINTER$ share set up to automatically add printer drivers to Win95 clients. It explicitly says that the procedure described does not work for NT4.0 clients. I can't find any other documentation on setting up a PRINTER$ share suitable for NT4.0 or NT2000 clients either in the distribution (2.0.5a) or the web site. Is this

Hi all, I would like to parallelize some R code and would like to use the 'foreach' package with a foreach loop. However, whenever I call a function from an enabled package outside of MASS, I get an error message that a number of the functions aren't recognized (even though the functions should be defined). For example: library(foreach) library(doSMP) library(survival) # Create the
