Help with Lattice
Hi: I have started to use Lattice two days ago and find that it is an outstanding package. I am, however, stumbling on two problems, despite the fact that I have read the help pages as well as two pdf documents on Trellis that I found on the web. 1- I want to remove the ticks on the top and right sides of the panels and did not see any option in "scales" to do so. 2- I would like

Help to check data before putting it in a database
The example scene: I have a database with stats about each goal made by my soccer team. This database (a data frame in R) is organized in lines (goals) with a set of columns containing data about these goals (player name, tactic position, etc). For now, this database will be called "data.frame1". What I need is to feed this "data.frame1" with new information about my team

More help with Lattice
Hi: Thanks a lot to Deepayan Sarkar, author of lattice I think, who solved my first query. I am afraid that I have another one. I am plotting several mutipanels boxplots (with one conditioning variable) on one page. The x, y and conditioning variable are all continuous variables. The x and conditioning variables are transformed to shingles before being plotted. The plot looks nice but there

Question about unicode characters in tcltk
hello list, Can someone help me figure out why the following code doesn't work? I'm trying to but both Greek letters and subscripts into a tcltk menu. The code creates all the mu's, and the 1 and 2 subscripts, but it won't create the 0. Is there a certain set of characters that R won't recognize the unicode for? Or am I input the \u2080 incorrectly? library(tcltk) m

add column with values found in another data frame
I am positive this problem has a very simple solution, but I have been unable to find it, so I am asking for your help. I need to know how to look something up in one data frame and add it as a column in another. If I have a data frame that looks like this: > frame1 ID score test age 1 Guy1 10 1 20 2 Guy1 13 2 20 3 Guy2 9 1 33 4 Guy2 11 2 33 and another frame that looks like this:

Merge and join data
Hi, I'm looking to combine two data frames. Several of the columns are in common while the others need to be summed up. The apply functions and the merge functions don't seem to be working. I've included a basic example of what I'm trying to do below. Thanks! Sean data.frame1<-as.data.frame(matrix(c('winter','dredge','515',100,150),1,5))

lda
I'm trying to do a linear discriminant analysis on a dataset of three classes ("Affinities"), using the MASS library: > data.frame2 <- na.omit(data.frame1) > > data.ld = lda(AFFINITY ~ ., data.frame2, prior = c(1,1,1)/3) Error in var(x - group.means[g, ]) : missing observations in cov/cor What does this error message mean and how can I get rid of it? Thanks! Pieter

This is a follow-up to bug sent to days ago, which bounced from r-devel because the example was to large. Now example is smaller, and behaviour is as belo, EXEPT that r-windows not any more bombs, so main problem is "xpdrows.data.frame"??? By the way, how to debug this example under windows? debug() doesnt accept the functions used (.Primitive), and R wont run under gdb --- may have

To draw observation [m, n] from 20 data frames named frame1, ... , frame20
Hi all, I have 20 data frames, named frame1, ... , frame20. Each data frame has the dimension 20x5. I need to build a function that calls out the observation in Row 1, Col 2 from all 20 data frames and places it in a vector of length 20. I have tried the following code: vect <- rep(0,20) for(i in 1:20){ vect[i] <- paste("frame",i,"[1,2]",sep="") } The

Simple Matrix plot question
Hello. I'd like to produce a simple pairs-like plot with two data frames - but not a traditional scatter-plot matrix - just multiple bivariate plots of data.frame1[i] vs data.frame2[i] ... In other words, given data frames X and Y, I'd like multiple plots on a page like: Y1 Y2 Y3 X1 X2 X3 Thanks in advance. -R

auto-detection of frame boundary
I tried feeding in the 3 encoded frame in ONE BLOCK, and calling speex_decode() 3 times in a roll. Only the 1st frames came out perfectly. For the other 2, I got "corrupt" frame warning. I was supposed to get 38 bytes consumed each frame (narrow-band, VBR off). I tried speex_bits_remaining() to peek on the # of bits consumed, and got variable (clearly wrong)#s returned. But if I
