Dear helpers, I'm trying to replace a character with a unicode code inside a data frame using gsub(), but unsuccessfully. > data.frame(animals=c("dog","wolf","cat"))->my.data > gsub("o","\u0254",my.data$animals)->my.data$animals > my.data$animals [1] "d??g" "w??lf" "cat" It's not that a data

Dear helpers, how can I extract only the values from a row in a data frame? Using [X,] doesn't do the trick: > data.frame(letters[1:10],letters[11:20])->my.data > my.data[1,] letters.1.10. letters.11.20. 1 a k I would like to be able to extract only the values "a" and "k" without getting the row names and column names with them.

Dear helpers, I can create a vector with the priority of the packages that came with R, like this: > installed.packages()[,"Priority"]->my.vector > my.vector base boot class cluster codetools "base" "recommended" "recommended" "recommended" "recommended" compiler datasets

Dear helpers, I'm trying to extract certain rows from a matrix according to the values the rows have in a certain column. I've been googling for a while without result. Here's a reproducible example of a matrix (and the one I was playing with initially): > myrepo<-getOption("repos") >

Hi all, I'm extracting the name of the term in a regression model that dropterm specifies as the least significant one, and I'm assigning this name to an object. However, when I use update(), it ignores this object. Is there a way I can make it not ignore it? A reproducible example is below: > lm(x1~1+y1*y2+y3+y4,data=anscombe)->my.lm >

Dear helpers, I'm trying out the embedFonts() to embed fonts into my pdf files. However, when I inspect the new pdf with a program designed to look for embedded fonts, I see that the fonts have in fact not been embedded. Below are my calls.

As recently discussed on Stack Overflow, R for Mac OS and Ubuntu (so probably all Unix systems) can correctly write files with UTF-8 encoding, but R for Windows cannot: http://stackoverflow.com/questions/19877676/write-utf-8-files-from-r I strongly suggest that R for Windows should support this feature in upcoming versions.

Dear helpers, I am not able to export Unicode characters from R. Below is an example where the Unicode character is correctly rendered as long as I am stay within R. When I export it, the character appears only with its basic code, and the same happens when I import it back into R . I'm using R 2.13.1 in Windows XP. > funny.g <- "\u1E21" > funny.g [1] "?" >

Full_Name: Bob O'Hara Version: 2.6.0 OS: Windows XP Submission from: (NULL) (88.112.20.250) Using horizontal=TRUE with boxplot() confuses it as to what is an x- or y-axis. At least, xlim= and ylim= are the wrong way round, log="x" (or "y") and xaxt= work as expected, I haven't looked at anything else. Some code to see if you can reproduce the bug (or discover

HI there, why these lines of code are correct plot(count~spray, data = InsectSprays) plot(InsectSprays$count) but this return an error: plot(count, data = InsectSprays); "data" method is not implemented in plot?!

I am using R 2.2.1 on a Windows 2000 PC. When I do a grid() after the boxplot it overprints the boxplot: > boxplot(count ~ spray, data = InsectSprays, col = "lightgray") > grid(nx=NA, ny=NULL) > if I try the panel.first > boxplot(count ~ spray, data = InsectSprays, col = "lightgray", + panel.first=grid(nx=NA, ny=NULL)) > I can see the grid flash

Hi, I would like to use the beanplot() function from the beanplot package. Unfortunately, I can't find out how to suppress the dashed horizontal line, that shows the overall mean. In the help I've found the argument "overallline", but it only allows for "mean" or "median" . I have tried overallline = F, overallline="n", and

Dear List-Members, I would like to produce a ordered boxplot in which the categories with the smallest median are plotted at the left end and the box with the largest median at the right. Thanks in advance for any advices Thomas H.

Dear R-users, Does anyone knows how I can order my serie of boxplots from lowest to highest median (which is much better for visualization purposes). thanks in advance, willem [[alternative HTML version deleted]]

Dear all - With the following code I get Boxplots and Stripcharts in one Plot: with(InsectSprays, boxplot(count ~ spray, boxwex = 0.3)) with(InsectSprays, stripchart(count ~ spray, col = "red", vertical = TRUE, add = TRUE)) But the dots from the stripchart are plotted over the Boxes. Is there any possibility to have Stripchart and Boxplots side-by-side, i.e. to move boxplots and/or

Estimados amigos, mi pregunta es bien directa, a ver si alguien me puede ayudar: Como marcar la media en un grafico boxplot ?? Por lo que veo, los boxplot en R marcan por defecto la mediana dentro de la caja, pero necesito marcar la media y ojala sacar la mediana para que no aparezcan los dos parametros. Por lo que he leido, imagino que se puede hacer con alguna funcion de bajo nivel, pero soy
