Dear (T)eXpeRts, I try to create a LaTeX table from an R matrix for the first time. I am not sure what the "best" approach is, I just read about latex() from Hmisc (toLatex() didn't work). Consider the following minimal example: library(Hmisc) mat <- matrix(c(1,NA,3,100,10000,4), ncol = 3, byrow = TRUE) latex(mat, file = "", booktabs = TRUE, numeric.dollar = FALSE,

I have a data set of many rows and many columns in which both the rows and the columns have associated grouping factors. Is there a way to do what 'aggregate' does but in the other dimension? The way I have been doing this is to use 'aggregate' on the data in the usual way and then rotate the result and apply 'aggregate' again. This works but is a little messy and I was

Hi everyone I have created a function that uses xtable to print table of frequencies and percentages with a heading and some sample information (the sample size and missing values). The function and example data is below. I want a vertical line that separates the results from the sample information i.e. a vertical line on the bottom of the line second from last

Dear expeRts, how can I decrease the space between the tick marks and the corresponding labels in an splom? See here: library(lattice) U <- matrix(runif(4000), ncol = 8) splom(U, axis.text.cex = 0.2) # => space between the [small] tick labels and tick marks is/seems to be too large I checked ?panel.pairs but could not find an option for that. Cheers, Marius

Dear expeRts, Here is a minimal example with the latest version of 'tables' (questions below): require(tables) saveopts <- table_options(toprule="\\toprule", midrule="\\midrule", bottomrule="\\bottomrule", titlerule="\\cmidrule(lr)", rowlabeljustification="r")#, justification="r") ## data.frame x

I've got a package I would like to send out for testing and have noticed a "problem" with the \tabular portion of the help "compiler" the code for inserting vertical lines, in the tabular environment, causes the build to choke, but not the check command. C:\>rcmd build --binary -docs=all nlsystemfit \tabular{|l|c|c|c|}{ \hline Method \tab Instruments \tab

Dear all, When using latex.table from the quantreg package, I don't seem to be able to set table.env=FALSE: when I don't specify caption (as I think I should, when understanding the R help rightly(?)), I get an error message, and when I do so, of course I get one, as well. The funny thing is, that a table is indeed produced in the first case, so I get a nice tabular, but as I'm using

Hi, This is most likely only a minor technicality, but I saw the following: On page 6 of the 'parallel' vignette (http://stat.ethz.ch/R-manual/R-devel/library/parallel/doc/parallel.pdf), the random-number generator "L'Ecuyer-CMRG" is said to have seed "(x_n, x_{n-1}, x_{n-2}, y_n, y_{n-1}, y_{n-2})". However, in L'Ecuyer et al. (2002), the seed is given with

Hi, why does format(10000, big.mark = "\\,") not give me "10\,000"? How can I get this kind of "big.mark"? Cheers, Marius

Dear expeRts, I would like to create a plotmath-label of the form X_1^\prime. Here is how to *not* do it [not nicely aligned symbols]: plot(0,0,main=expression(italic(X*minute[1]))) plot(0,0,main=expression(italic(X[1]*minute))) plot(0,0,main=expression(italic(X)[1]*minute)) Any suggestions? Cheers, Marius

Dear expeRts, How can I vertically adjust an axis tick label so that it is nicely aligned with the other labels? library(lattice) xyplot(0~0, xlim=c(0,3), scales=list(x=list(at=c(1,1.1), labels=c(expression(hat(theta)[italic(n)]),expression(theta))))) ## aim: move the leftmost expression up so that theta is nicely aligned with the second theta. Cheers, Marius

Hi Simon, thanks for your quick reply. 1) ... so you can reproduce this? 2) Do you know a way how this can be 'foreseen'? We allocate larger matrices in the copula package depending on the user's input dimension. It would be good to tell her/him "Your dimension is quite large. Be aware of killers in your neighborhood"... before the killer attacks. Thanks & cheers,

Dear expeRts, I have two matrices A and B. They have the same number of columns but possibly different number of rows. I would like to compare each row of A with each row of B and check whether all entries in a row of A are less than or equal to all entries in a row of B. Here is a minimal working example: A <- rbind(matrix(1:4, ncol=2, byrow=TRUE), c(6, 2)) # (3, 2) matrix B <-

Dear expeRts! when I try summarize data using "tabular" of tables package.. here is an example.. > a <- data.frame(a=rep(10,10),b=round(runif(10,10,20)),c=round(runif(10,40,50))) > a a b c 1 10 14 44 2 10 17 40 3 10 13 40 4 10 18 40 5 10 11 49 6 10 16 46 7 10 15 43 8 10 19 49 9 10 19 49 10 10 13 45 > tabular((a+1)~(n=1)+Format(dig=0)*(b + c) * (mean +

Dear expeRts, I would like to colorize the backgrounds of a pairs plot according to the respective panel number. Here is what I tried (without success): count <- 0 mypanel <- function(x, y, ...){ count <<- count+1 bg. <- if(count %in% c(1,4,9,12)) "#FDFF65" else NA points(x, y, cex=0.5, bg=bg) } U <- matrix(runif(4*500), ncol=4) pairs(U, panel=mypanel) I

Dear expeRts, I would like to create a scatter plot matrix with splom(). The lower panel should contain some additional information about the samples shown in the upper panel plot, see the splom() call below. Now two questions came up: (1) The lower panels show "tau" and "alpha" on top of each other. How can I plot *three* expressions on top of each other? I tried several

Dear expeRts, How can I increase the space between the ticks and the labels in the wireframe plot below? I tried some variations with par.settings=list(..) but it just didn't work. Many thanks, Marius library(lattice) u <- seq(0, 1, length.out=20) grid <- expand.grid(x=u, y=u) z <- apply(grid, 1, function(x) 1/(x[1]*x[2]+0.0001)) wireframe(z~grid[,1]*grid[,2], aspect=1,

Dear Rxperts, q <- data.frame(p=rep(c("A","B"),each=10,len=30), a=rep(c(1,2,3),each=10),id=seq(30), b=round(runif(30,10,20)), c=round(runif(30,40,70))) The operation below... tabular(((p=factor(p))*(a=factor(a))+1) ~ (N = 1) + (b + c)* (mean+sd),data=q) yields some rows of NAs and NaN as shown below b c p a N mean sd mean sd A 1 10

Hi, Both under the current R-devel (r66456) and a version from about 3 months ago, I experience the following behavior: > parallel::detectCores(TRUE) Error in system(cmd, TRUE) : error in running command > traceback() 3: system(cmd, TRUE) 2: gsub("^ +", "", system(cmd, TRUE)[1]) 1: parallel::detectCores(TRUE) > This is on Ubuntu 14.04.

Hi, Interesting "feature" in 10.11.4. I wonder if the process is killed before or after malloc() returns. If before, it seems very blunt: "You're asking too much and I don't like it so I kill you now". If after it doesn't look much better: "You're asking a lot and I don't like it but I give it to you anyway. I'll kill you quickly later". Why
