Hi, My R has been installed on a Ubuntu linux computer in Germany. The error messages I get are in German, for example: In min(magnitudes) : kein nicht-fehlendes Argument f?r min; gebe Inf zur?ck I would like those to be displayed in English, for pasting them into google. I tried searching for "R language", which brings me a ton of results for.. well, the R language :) "R german

Hi, I'm trying to write a function to determine the euclidean distance between x (one point) and y (a set of n points). How should I pass y to the function? Until now, I used a matrix like that: | [,1] [,2] [,3] [1,] 0 2 1 [2,] 1 1 1 | Which would pass the points (0,2,1) and (1,1,1) to that function. However, when I pass x as a normal (column) vector,

Hi, I am implementing a function which generates about 10 .pdf plots in the current directory. I need the graphic to fit into a LaTeX-Presentation-slide, so the outer margin should be removed (this is the way to do it, right?): I am having trouble finding out where to put the par command(s). Is one enough or should I put them before and after /every/ plot() command? This is how I tried to do

Dear List, how can I obtain the value of r suqared for a non-linear model? For linear models it can be found in the summary() of the model but for non-linear models I just don't know. Please help! Anna

I run into some problems when trying to convert units using Hershey-Fonts: R chrashes. > library(grid) > label <- "some text" > pushViewport(viewport(gp=gpar(fontfamily="HersheySerif"))) > convertHeight(stringHeight(label), unitTo="mm") *** caught segfault *** address 0xadc838f8, cause 'memory not mapped' Traceback: 1:

Dear list, Consider the following, library(grid) w = unit.c(unit(1, "in"), unit(2, "in")) w2 = w + unit(1, "mm") w[2] <- 0 w2[2] <- 0 convertUnit(w, "mm") #[1] 25.4mm 0mm convertUnit(w2, "mm") #Error in grid.Call("L_convert", x, as.integer(whatfrom), as.integer(whatto), : # INTEGER() can only be applied to a

Dear R Users: I'm a STATA user converting to R, and I'd like to be to do the following. #Assign var_1 and var_2 a value 10->var1 20->var2 #Now I'd like to print the values of var_1 and var_2 by looping through var_1 and var_2 in such a manner: while(y<3){ print(var_y) y+1->y } In STATA, the "y" appended to " var_" is called the local variable and

I'm presumably missing something very obvious, but how does one use the key.opts argument in labcurve (via Ecdf)? In this example, I want the key to be big and have a blue background, but it isn't and doesn't. ch <- rnorm(1000, 200, 40) sex <- factor(sample(c('female','male'), 1000, TRUE)) Ecdf(~ch, group=sex, label.curves=list(keys=c("f",

Hello, I have a dataframe (var_1, var_2, ..., var_n) and I would like to export summary statistics to Latex in the form of a table. I want specific summary statistics by crossing numerous variables 2x2 AT ONCE. In each cell I would like sometimes to have the median (Q1 - Q3), or frequency and proportion, etc. CrossTable, xtab, etc... do not allow for multiple 2 by 2 crosstabulation. The table

Hello, I'm new to R and have a very basic syntax question for the functionglm. I am using the function glm() to do a regression on a data set. I want to run this function in a while loop, so I need to be able to do two things: (1) I need to be able to have my list of variables in the regression be based from a variable vector instead of hard code. (2) I need to be able to collect the

Dear all, I'm puzzled by the behavior of stringHeight in the grid package. Consider the following test, library(grid) test <- function(lab="dog", ...){ g1 <- textGrob(lab) g2 <- rectGrob(height=grobHeight(g1), width=grobWidth(g1)) gg <- gTree(children=gList(g1,g2), ...) print(c("height:", convertUnit(stringHeight(lab), "mm",

During last update packets pidgin and libpurple were updated while "yum update"-ing Is it a common and normal thing that both x86_64 and i386 arch rpms are installed during update? This not the first time. -- Cheers, Alexx mailto:alexx187 at gmail.com

Buenas tardes, Quiero aplicar la función rbind y necesito tener los mismos nombres de columnas. Como tengo unas 195 variables en cada dataframe, necesito hacerlo de una forma rápida. Tengo 9 bases de datos y tengo que fusionar todas. ¿Como puedo comprobar que los nombres de las variables son los mismos? Y de lo contrario, ¿como detecto las diferencias? He probado con

Hi! This is a really weird problem, I hope, someone can help me out there. First of all, I put my smb.conf on the web, you can find it here[0]. The Sambaserver (ESS-LINUX) is just an ordinary workstation (in the terms of SMB) and uses the PDC (ESS_SERVER) for authentication (see "password server"-directive). Nearly everything works fine. Each authenticated user gets his home-directory

Hello, I tried to install CalamusSL 2000 under wine 20010305 and the installation itself was successfull. But when I start the program the main window is very small (120x27) and can't be changed. So the GUI is not visible ... What can I do to help the maker of the program to find the problem? And there is another problem with temporary fonts. The program needs some fonts that will be

Hi: (Tried to find a bug report about this issue, but was unable to find it, let me know if this is a known issue) I have been working on an interface to highlight xyplot panels on mouse overs in JavaGD but I have stumbled with what seems to be a bug in trellis.focus. I am using R 2.8 with lattice 0.17-15 *** To replicate the bug: 1.- display an xyplot. For example, from the xyplot help page:

Hi All, I have been able to modify the x-axis to start at zero by adding xlow and xhigh parameters; that was pretty simple. I have been unable to find the location of the code that would turn off the information weighting of the box size (I have smaller randomized trials getting less weight than a much larger non-randomized trial). The function is forestplot() from rmeta. Thanks for any

Hi all, I'm trying to generate a plot containing a scatterplot, with marginal densityplots for x and y. However, when I try to generate a vertical densityplot, I get the message "warning: can't clip to rotated viewport", and nothing shows up. I'm probably misunderstanding how viewports are meant to be used, so if someone could give me a hint, I'd be most grateful. my

Hello! I first would like to compliment the authors of grid on what has been a wonderfully useful package for me. Now, my question: Is there any way I can specify the size of some grid.text using grid units? I must label the regions of a plot. The regions can be either very small or very large, so I would like to label each by fitting its text to the size of the region in question. Ideally, I
