Re: [R] printing a variable during a loop

If you are using the Windows GUI you can turn 'output buffering' on and off by either typing Ctrl-W or by using the MiscOutput Buffering menu item. When output buffering is off you may not need to add flush.console() to your code. Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com

[R] Conditional looping over a set of variables in R

Here's the problem I'm trying to solve in R: I have a data frame that consists of about 1500 cases (rows) of data from kids who took a test of listening comprehension. The columns are their scores (1 = correct, 0 = incorrect, . = missing) on 140 test items. The items are numbered sequentially

Re: [R] getting all contrasts from glm

Jim, In the glm object I can find the contrasts of the main treats vs the first i.e. 2v1, 3v1 and 4v1 ... however I would like to get the complete set including 3v2, 4v2, and 4v3 ... along with the Std. Errors of all contrasts. Your best all round approach would be to use the multcomp

[R] scale,centre,and get more interactions

Hi folks, I am new to lme in R, and I have a question regarding to the effect of scale function on the lme. When I use the function to scale and centre the levels of the fixed effects (e.g., X and Y; both have two levels) and write them to new columns: ex: dat$cX-scale(as.numeric(dat$X),center =

[R] Interpolate irregular time series

Hi all, Issue: I have two datasets, one is a regular time series (rain gauge) with resolution of 10 minutes. The other one is an irregular time series (link). Now I want to analyze the correlation between these two datasets with linear regression. The regular time series is a data.frame and

[R] FitARp

Dear R users, I have a data set with time series as continuous (time(day of measurement) = 1,7,14,21...), for each time I have measured height in a total of 100 individuals. I would like to correlate height with chlorophyll content (single measurement per individual), and for that I would

[R] using gedit

Dear all, I'm using R (2.10.1) under Ubuntu (9.10) and, as I don't like vi, I edit my functions with the command : edit(.,editor=gedit) which works fine, except when gedit happens to be already running. Then a new tab is created, and on exit all changes are lost, regardless if I close the tab or

Re: [R] how fit linear model with fixed slope?

Hi, It looks to me like you want to fit x as an offset (i.e. a variable with a fixed gradient of 1). If so, simply do: lm(y~1+offset(x)) #for a model with an intercept or lm(y~-1+offset(x)) #for a model with no intercept Cheers, Nick -Original Message- From:

Re: [R] Conditional looping over a set of variables in R

David, here I'm referring to your data as testmat, a matrix of 140 columns and 1500 rows, but the same or similar notation can be applied to data frames in R. If I understand correctly, you are looking for the first response (column) where you got a value of 1. I'm assuming also that since your

Re: [R] Conditional looping over a set of variables in R

You were a bit vague about the format of your data. I'm assuming all columns were numeric and the entries are one of 0, 1, and NA (missing value). I made a little function to generate random data of that format for testing purposes: makeData - function (nrow = 1500, ncol = 140, pMissing = 0.1)
