converting factors to dummy variables
Hi all - I'm trying to find a way to create dummy variables from factors in a regression. I have been using biglm along the lines of ff <- log(Price) ~ factor(Colour):factor(Store) + factor(DummyVar):factor(Colour):factor(Store) lm1 <- biglm(ff, data=my.dataset) but because there are lots of colours (>100) and lots of stores (>250), I run it to memory problems. Now, not every

Vista problem -- can't type commands at prompt
Hi All - I recently moved to Vista and reinstalled R. I am able to run R as I typically do (R.exe from the command prompt), and it can work well. However, if I switch windows to, say, firefox or excel or anything else, when I return to the R prompt it no longer works. I am able to use the up and down arrow keys to access previous commands, but no other key stroke has any impact. As long as I

Definition of "wrapper"?
I think I more or less understand what a ?wrapper? is, but I?d like to hear how more experienced R users define it, and especially I'd like to know if there is a formal definition. In my reading, it seems like there are a fairly wide range of meanings, but they are all conceptually similar. I've looked in a couple of the classic R texts, the extensions and developers' manuals, and R

grDevices::convertColor XYZ space is it really xyY?
grDevices::convertColor has arguments 'from' and 'to' which can take on value 'XYZ'. Can someone confirm that 'XYZ' is the same as the CIE chromaticity coordinates that are also sometimes refered to as 'xyY' in the literature? Or are these the CIE tristimulus values? It looks to me like the first case is true, but I would appreciate hearing from one of

Help with lm and multiple linear regression? (Plain Text version)
(Apologies the previous version was sent as rich text) Hello, I'm new to R, but I've read the intro to R and successfully connected it to an instance of mysql. I'm trying to perform multiple linear regression, but I'm having trouble using the lm function. To start, I have read in a simply y matrix of values(dependent variable) and x matrix of independent variables. It says both

Where are usages like "== 2L" documented?
Gurus: I keep seeing other people?s code that contain ideas like If (x == 2L) X[-1L] X - 1L I have some idea of what?s going on, but where is the use of concepts like ?2L? documented?

Selecting/Accessing the last vector in a list of a list of data.frames

Replacing several rows of a matrix at once
Hello Folks. This must be a silly question with a (not) obvious (to me) answer. Consider this: tmp <- matrix(1:200, nrow = 20) vec <- 300:309 tmp[9,] <- vec # replacing one row works fine p <- c(3, 11, 17) tmp[p,] <- vec # replacing multple rows pastes the values down a column and recycles vec. What I want to do is replace multiple rows simultaneously at once. I suppose I can

Lattice Version of grconvertX or variant on panel.text?
Still playing with Lattice... I want to use panel.text(x, y etc) but with x and y in plot coordinates (0,1), not user coordinates. I think if I had this problem with traditional graphics, I could use grconvertX to make the change. I did come across convertX {grid} but this doesn't seem to be what I need. Is there a function like grconvertX in Lattice, or is there a flag or some other

Why doesn't vec[-real.number] give an error or warning? Kids do the darndest things!
Hi all... My students were conflating grepping for a value in a vector to get the index, and then removing it with [-index], for instance like this: set.seed(17) v <- rnorm(20) s <- v[-1.18] They were trying to remove the 12th value in v, which is -1.18 or so. But the result is, as documented in ?Extract, to coerce 1.18 to the next lowest integer, and remove the 1st value of v, not the

plotmath: unexpected SPECIAL
Hello R Masters and the Rest of Us: The first of these works fine, the 2nd is accepted but too literal (the "%->%" is shown in the plot label and in the wrong position). The 3rd throws and error due to "unexpected SPECIAL". Would someone recommend a way to format this? I want the two phrases connected by a right arrow. TIA, these things always elude me. Bryan

Writing a function, want a string argument to define the name of the excel sheet to be called
My question is this: is there a way I can make one of the arguments of the function be a string the user can enter, and then have that be the excel filename? ie, foo <- function(x,y,NAME){ #make a matrix with x rows and y cols M <- matrix(nrow=x,ncol=y) #write the matrix write.table(M, file = "result.csv",append=TRUE, sep = ",") } I've had a look but I

xyplot {lattice} are different types possible for each panel?
Hello R Folks... Using the example below, I¹d like two of the panels to be plotted with type = ³p² but the third to be done with type = ³h². I can¹t use type = c(³p², ³p², ³h²) because this syntax applies all given types to every panel. I don¹t think I can use groups and distribute.type because these are intended for different styles of plotting within a single panel. As you can see, I tried

ggplot2, building a simple formula interface
I?m trying to build a simple formula interface to work with a function using ggplot2. The following scheme ?works? up until the plot(p) request, at which point there are complaints about xlim?s and a blank graphics window. Looking at str(p) I do see the limits are NULL, plus layer 1 claims to have an empty data frame (but df is reproduced correctly). I'm sure I'm missing something really

Teasing out logrank differences *between* groups using survdiff or something else?
R Folk: Please forgive what I'm sure is a fairly na?ve question; I hope it's clear. A colleague and I have been doing a really simple one-off survival analysis, but this is an area with which we are not very familiar, we just happen to have gathered some data that needs this type of analysis. We've done quite a bit of reading, but answers escape us, even though the question below

Downloading a csv from Dropbox using the shareable link
Hello Kindred R Spirits... I'm trying to get a file (csv) from Dropbox using their shareable link concept. They issue a short URL that goes to a web page where you see a button that says "Download File". They don't really give you the URL of the file itself, just this page. Is there a way to coax R into getting such a file? I don't even really want the file per

findInterval and data resolution
Hello Wise Ones... I need a clever way around a problem with findInterval. Consider: vec1 <- 1:10 vec2 <- seq(1, 10, by = 0.1) x1 <- c(2:3) a1 <- findInterval(x1, vec1); a1 # example 1 a2 <- findInterval(x1, vec2); a2 # example 2 In the problem I'm working on, vec* may be either integer or numeric, like vec1 and vec2. I need to remove one or more sections of this vector;
