Hi, I have managed to format my data into a single datframe consisting of two AsIs response and predictor dataframes in order to supply the plsr command of the pls package for principal components analysis. When I execute the command, however, I get this error: > fiber1 <- plsr(respmat ~ predmat, ncomp=1, data=inputmat,validation="LOO") Error in model.frame.default(formula =

Well, the title says all for this one. It seems to crash the R-console, so it happens whether I use the R-gui or R-console directly or Emacs with ESS. I have R 2.9.0 on Windows Vista. Thanks, Vassilis

Hello everyone, I am trying to prune a data frame for partial least squares analysis. I need to delete an entire row if one cell in the row contains a NA. Presently, I am running a loop that is supposed to extract the rows that are full of numbers into a second data frame and skips the rows that contain a single NA value. I want to know if there is a simple way to determine if a row

Hi, How do I use the string content of a string variable to reference a data frame of the same name? I want to do the typical tasks of 1) building a name with a string variable and using the string variable to create a data frame (or any object) whose name is the string value of the variable and 2) pass on a string to a function as a parameter, and then use that string to refer to an existing

Hello everyone, I have a couple of fairly simple questions (I hope) the answers to which I cannot find through the documentation at the moment. 1. I would like to delete the a row from a matrix if a certain elimination criterion is met. I am familiar with x <- x[-7,] (to remove row 7, for example). Are there any other means of removing an entire row? 2. Is there a single command that

Hello, Is possible to place a label on a multipanel figure outside the boundaries of any single one of the existing graphs in a panel? Specifically, I have a function that creates a panel with quartz() and then fills it with 6 graphs consisting of exactly the same plot for 6 different groups. I would like to add one title for the entire figure at the top of the figure, but I cannot figure out

Hi, I have written boxplot commands of this form before, but I don''t quite understand why the function call is reporting a syntax error in this instance. All parameters passed to the function are strings. Thanks in advance. Payam > simplevar <- function(wframe,column1,column2) { + tframe <- get(wframe) + x1 <- which(names(wframe)==column1) + x2 <-

I have encountered a more fundamental problem in my data set. I''m using read.csv, and all the data are imported as character.

Hello, I have created a .dll file using G77 and MinGW on my PC (Windows 2000). After using dyn.load to bring it into R2.0.1, I then call the .dll through the function ccprox shown below. It returns the correct values. If I run it a second time though it returns different values, so it seems something is being placed oddly in memory. If I unload and reload the .dll it works again the first

Dear list, This must be an easy one.
