Hello, What is the best way to turn a matrix into a list removing NaN's? I'm new to R... Start: > mt = matrix(c(1,4,NaN,5,3,6),2,3) > mt [,1] [,2] [,3] [1,] 1 NaN 3 [2,] 4 5 6 Desired result: > lst [[1]] [1] 1 3 [[2]] [1] 4 5 6 Thanks! Ben [[alternative HTML version deleted]]

Hello, I'm attempting to return the date (in form '%Y-%m-%d') of the Monday previous to the current date. For example: since it is 2011-09-02 today, I would expect 2011-08-29 to be the return value. I found the following in: http://www.mail-archive.com/r-help@r-project.org/msg144184.html Start quote from link: prevmonday <- function(x) 7 * floor(as.numeric(x-1+4) / 7) +

Hello, I have a bunch of data files all with "dbs" file extensions. They are generated via a SQL query from another program and source. Does anyone know (or have ideas) how to get the data from a dbs file type into R (or into some other format that can imported to R)? I've searched online for 4 hours now... Thanks!

Can someone show me how to modify one (R.oo) class's object inside another (R.oo) class's method? Is that possible with the R.oo package? A quick example or reference to an example would be outstanding... Thanks, Ben [[alternative HTML version deleted]]

Hello, Does anyone know how to convert this: > msg [1] "a" [2] "b" [3] "c" To: > msg "a b c" In other words, I need to convert a character vector to a single string with carriage returns for each row. Functionally, I'm attempting to send an email of a character vector in a way that is readable in the email body. I can only input one

Hello, Why does rm.outlier produce a list for me? I know its something about my data because I can't make a mock up that reproduces the issue. Any ideas? My data goes in as a matrix and comes out as a list: > class(dat) [1] "matrix" > dat = rm.outlier(dat) > class(dat) [1] "list" > Thanks, Ben [[alternative HTML version deleted]]

Hello, There has to be a more R'ish way to do this. I have two matrices, one has the values I want, but I want to NA some of them. The other matrix has binary values that tell me if I want to NA the values in the other matrix. I produce a third matrix based on this. I've also tried apply() passing in c(1,2) for rows and columns with no success yet. Example (this works, but I'm

Hello, Does anyone know how to change the Tinn-R editor background color? White is rough on the eyes... Thanks, Ben [[alternative HTML version deleted]]

Hello, Using the rgl package, I can set the device window to any dimension (that I have tested): par3d(windowRect=c(1,1,700,700)) With windows I can't get the window to span from the top to the bottom of the monitor. In the following, no matter how large the ypinch value gets it stops, leaving about 2 inches of space at the bottom of my screen: windows(record=TRUE, ypinch=1100, xpinch=10,

Hello, I'm looking for help putting an interactive rgl package 3d device on the web so that it maintains full functionality. Where should I start? Is it possible? Is there an example I can see? (Note: I'm also looking at putting other normal plots on the web.) I'd like to stay within R as much as possible... I didn't find much online regarding rgl 3d plots. Thanks, Ben

Hello, I'm trying to get the count of values in each row that are above and below quantile thresholds. Thanks! Example: > x = matrix(1:30,5,6) > x [,1] [,2] [,3] [,4] [,5] [,6] [1,] 1 6 11 16 21 26 [2,] 2 7 12 17 22 27 [3,] 3 8 13 18 23 28 [4,] 4 9 14 19 24 29 [5,] 5 10 15 20 25 30 > qtl = t(apply(x, 1,

Hello, I'm looking to get the values, row names and column names of the largest and smallest values in a matrix. Example (except is does not include the names): > x <- swiss$Education[1:25] > dat = matrix(x,5,5) > colnames(dat) = c('a','b','c','d','c') > rownames(dat) = c('z','y','x','w','v') >

Hello, I'd like to 'do work' on data members upon construction (i.e. without implementing it in a get method). Is this the best way to create data member 'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex I'll run into issues. setConstructorS3("MyClass", function(x=NA,y=NA,...) { this <- extend(Object(), "MyClass",

Hello, Using the R.oo package, how do I throw an error if a field is not present when the user of the class creates the object? Using the example in the R.oo package: setConstructorS3("Person", function(name, age) { if (missing(name)) name <- NA; if (missing(age)) age <- NA; extend(Object(), "Person", .name=name, .age=age ) }) [rest of class methods

Hello, First time posting to this mail list. I'd like to use R in the most efficient way. I'm accomplishing what I want, but feel there is a more R'ish way to do it. Just learning R. *My goal: get ranks of value across rows with row names and column names intact.* I'm guessing one of the [?]apply functions will do what I need, but I couldn't sort out which one (after a lot

Hello, I'm using the rgl package and plotting a plot with it. I'd like to have all the axes values auto-hide, but I want to plot a series of characters instead of the values of the measurement for 2 of the axes. So in the end I will have one axis (z actually) behave per normal (auto-hide) and I'd like the other two axes to be custom character vectors that auto-hide. Example: x <-

Hello, I've posted something similar under a different subject and never received a solution. Trying again with (hopefully) a better description. Objective: Send a matrix of string data in an email message. The message must have authentication and be sent via an R script. I'm almost there! Here is where I am at: I collect long error message lines in 'errs', which is a matrix.

Hello, I have two data frames. One is my dependent variable and the other is my independent variable. For each row I'd like to split the independent variable into fractiles (25 or more) and calculate the average value of the dependent variable. Then I would like to plot the average of the averages for each row for each fractile. If possible, I'd like to have the option to 1) define the
