[R] Windows Installation Without Third-Party Packages

I am trying to install R for Windows, but when I use the installer provided on CRAN, a number of third-party packages are installed by default (i.e. lattice, Matrix, codetools, etc.). If R is installed with administrator privileges, so it's available for all users, non-administrators can't update t

Re: [R] Repeated Aggregation with data.table

ean(z)), by = eval(parse(text = sprintf("list(%s)", paste(x, collapse=","] I think that's a pretty ugly solution (although it does work), but I haven't come up with anything better. Any suggestions? Thanks. - Elliot On Tue, Sep 11, 2012 at 11:33 AM, El

[R] Repeated Aggregation with data.table

can reuse, similar to the function "f" above. Can someone please explain how to do that? Thanks. - Elliot -- Elliot Joel Bernstein, Ph.D. | Research Associate | FDO Partners, LLC 134 Mount Auburn Street | Cambridge, MA | 02138 Phone: (617) 503-4619 | Email: elliot.bernst...@fdopartner

[R] Error Installing Package with Dependency on "Matrix"

failed for package ‘temp’ * removing ‘/home/ebernstein/Rlib_2.15.1/temp’ If I remove the dependency on "Matrix", it installs fine. I'm using R 2.15.1 on linux, and version 1.0-6 of the Matrix package. Can anyone explain what's going on here? Thanks. - Elliot -- Elliot Joel Bernste

Re: [R] Thinning Lattice Plot

just call the "histogram" function with a different prepanel and panel function. Is it not considered a lattice plot only because it isn't part of the lattice package? Thanks. - Elliot On Tue, Jul 31, 2012 at 2:32 AM, Deepayan Sarkar wrote: > On Tue, Jul 31, 2012 at 2:43 AM, El

[R] Thinning Lattice Plot

possible to see that much detail. For example: require(Hmisc) x <- rnorm(1e6) pdf("test.pdf") Ecdf(x) dev.off() The resulting pdf files is 31MB. Is there any easy way to get a smaller pdf file without having to manually prune the dataset? Thanks. - Elliot -- Elliot Joel Berns

[R] combineLimits and Dates

[R] "Tight" Axes in Prepanel Function

How do I specify a "tight" y-axis, where the plot completely fills the y-axis range, inside the prepanel function? For example, consider the following code: require(lattice) set.seed(12345) x <- 1:1000 y <- cumsum(rnorm(length(x))) prepanel.test <- function(x, y, groups = NULL, subscripts = NUL

[R] splom Tick Location

When using the 'splom' function of the 'lattice' packge, is it possible to get all the tick marks in the outer margins of the plot? X <- as.data.frame(matrix(rnorm(1000), 100, 10)) plot(X) ## Tick marks are in the outer margin splom(X) ## Tick marks are inside the on-diagonal panels Thanks. - El

[R] Errors and line numbers in scripts?

Is it possible to get R to report the line number of an error when a script is called with source()? I found the following post from 2009, but it's not clear to me if this ever made it into the release version: ws wrote: >* Is there a way to have R return the line number in a script when it errors

[R] Cumsum in Lattice Panel Function

nt the result to look the same as if I had done dat$cumvalue <- with(dat, unsplit(lapply(split(value, group), cumsum), group)) xyplot(cumvalue ~ date, data = dat, group = group, type = 'l', grid = TRUE) Thanks for your help. - Elliot Elliot Joel

I'm trying to write a generic function that calls different methods depending on the structure of the argument, but not the exact type of its contents. For example, the function 'nan2last' below works for a numeric vector but not for a vector of Date objects. Is there any way to make it work on
