Hello, I would like to use by to create a series of plots, but I'm not sure how to design the function. Here's what I've got: 1. A data frame of observations of measured value 2 measured vlaues and a pch code. V1 V2 pchCode .0045 123 1 .0034 145 2 .0045 123 1 .0046 167 3 ... So what I want to do is create a single scatterplot of the multiple conditions (specified by

Hello all, I've got a bunch of objects I'd like to write to .csv files. For example, I have objects conveniently called n002.csv n001.csv p103.csv . . . I tried a loop: > for(i in ls(pattern="csv")) +write.table(i, file=i, sep=",", quote=F) That, of course, wrote out a bunch of files that contained x 1, n002.csv Or the like. How can I get i in the loop above

Hello, I have been trying to use by to create a means table, but receive the error " by(xx, list(subjs, cons, vowels), mean) Error in Summary.data.frame(..., na.rm = na.rm) : only defined on a data frame with all numeric or complex variables" when the data frame consists of three factor columns (subjs, cons and vowels) and 5 numeric data columns. The output I'm looking for is a

Hello, I'm attempting to classify data using tree(). summary(tree()) indicates that I have a very good classification rate. What I'd like to know is which tokens in the data set are correctly classified and which are not. Is there a method for associating the classification with the token? I've been reading Chambers and Hastie (1992) chapter 9 on tree-based models, but find no

Dear List, I would like to add captions to a set of graphics. The graphs are each composed of two scatter plots in an upper and lower pane. I'd like to add a caption below the lower pane. The troubel I'm hitting is that in order to fit the caption using mtext, I must increase the margins for both panes-- these shrinks my plots considerably and leaves a big blank area. The second trouble

Hello, Is there a function for searching a string for a given character? For example, I have transcriptions like tsibi tSibi tibi kibi I want to search the character object for the presence of 's' or 'S' or 'k'. I thought perhaps pmatch(c("k", "S", "s"), x) would work for me, but it wants to compare from the start of the string and returns

Dear List, I'd like to run a discriminate analysis on a data set, but have no idea how to go about this in R. I have attempted to locate info in the manuals, but may not be consulting the right sections or documents. Can anyone point me to appropriate documentation if such exists. Many thanks, David S.

Hello, I have downloaded and installed e1071_1.1-0.tar.gz, my first add-on package. Because I am not the sys admin I installed it to my own home dir under ~/.R/library/ I read in the faq that I should make changes to the R_lib env variable in my .bashprofile or .Renviron files to make the new personal library components available. Unfortunately neither of these exist in my home dir. Can anyone

Hello all, I have a simple question: I have filenames that look like these: "n031ku09.10msmeanc" "n031ku10.10msmeanc" "n031ku11.10msmeanc" [22] "n031ku12.10msmeanc" "n031ti01.10msmeanc" "n031ti02.10msmeanc" I also have a set of the same without the "c" at the end. When I run list.files(".",

Hello R-list, I have a batch of files that I want to turn into R data.frames for analysis. I'd like to use a for loop to read.table into data frame and name the data.frame after the source file. Here's the code I've tried: files_list.files(".") for(i in 1:length(list.files("."))-1){ parse(text=files[i])[[1]]_read.table(files[i],as.is=TRUE) } AFIK, the problem

Dear R-List, How can one look up the row/column number for a given value in a matrix or data.frame? For example in a matrix that contains only unique values for in [,1] how can I find value x in [,1] and report its row number? TIA, David S.

Hello R-list, I've been using hist to plot histograms of some data, but I get variable numbers of bins. I understood from reading the help file that breaks will set the number of bins. Please correct me if I'm wrong. I'm plotting measures from subsets of a larger data set. Depending on the data subset the number of bins varies despite having set breaks to 5 in all cases. See

Hi all, I figured out some things about an earlier question I posted today; this is a new question: I have a for-loop in which I have the following lines for (i in list.files(pattern = "*.dmp")) { currentfile <- read.table(i) vecrawrts <- as.vector(currentfile$V3) ... } Now, vecrawrts is numeric, but if I run the script on all the files with extension .dmp, I get the

I have this 'odd' problem; I need to let R pause, for a given time, before starting next iteration in a loop. I'm using the following to do this task, but feel a little bit guilty because I'm using as much CPU time as I can get while pausing: while(keepGoing) { t.end <- proc.time()[3] + 5 ## the time this loop should end at [block of R commands] while(proc.time()[3]
