Given an arbitrary data frame, it is easy to exclude a column given its index: df[,-2]. How to do the same thing given the column name? A naive attempt df[,-"name"] did not work :)

Dear All, Perhaps, what I am asking is impossible, but I am asking it anyway. I have got several pdf files with rows of colored rectangles: red rectangles should be read as 0; green rectangles as 1. No other color exists. Is there some way to have R reading the colored rectangles to a matrix or data frame converting the color of the rectangles to sequences of 01? Thanks in advance, Paul

Searching the mail archives I found that using legend.position as in p.ring.3 + opts(legend.position="top") is a known bug. I tried doing p.ring.3 + opts(legend.position=c(0.8, 0.2)) which works, but the legend background is transparent, i.e. I see the plot background through the legend. Adding additional option opts(legend.background=theme_rect(fill=TRUE,colour="white"))

I have a large data-frame with measurements such as: id i v1 v2 v3 1 1 1.1 1.2 1.3 1 2 1.4 1.5 1.6 1 3 1.5 1.7 1.8 2 1 2.1 2.2 2.3 2 2 2.7 2.5 2.6 2 3 2.4 2.8 2.9 For each unique value of 'id' (which in the real data-set is a combination of three variables) I want to compute the median of v1 within each group ('i' distinguishes measurements within a group), and copy the

I have a following problem: The call qplot(wg, v.realtime, data=df.best.medians$gv1, colour=sp, geom="boxplot") works nice: for each value of the wg factor I get two box-plots (two levels in the sp factor) in different colours, side-by-side, centered at the wg x-axis. However, I want to separate the data belonging to different levels of the n factor, so I add the facets option:

I have a data-set that is structured as follows: sp wg n v.realtime v.cputime v.tcputime v.idletime v.nswtch 9 0 1 1 28.61300 28.61 28.6039 0.00000e+00 407 1563 0 1 2 15.20270 30.38 28.5981 9.80523e-01 483 3128 0 1 4 12.50930 50.00 28.6053 1.07877e+01 489 4682 0 1 6 12.10260 72.55

Dear R People: Is it possible to run R on a netbook/mini, please? Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess at gmail.com

I use the following function to export some figures to .eps: p.eps <- function(p, fname, title = NULL, width, height) { postscript(file=fname, onefile=FALSE, paper="special", width=width, height=height, horizontal=FALSE) print(p + opts(title = title)) dev.off() } Whenever I have a page consisting of *only* figures exported in this way, Acrobat Reader shows them in

I have three plots and I want the *plot area* to be of the same width on each plot. Since the three plots have different legends, the text width of the legend affects the width of the plot area (longer legend text = narrower plot area). Exporting the three figures to postscript device of same size gives thus unequal plot areas. How can I calculate the correct width of postscript device for each

Hi All, Can anyone please help me with getting a single x and y-axis label while plotting muliple plots. Here is the code: par(mfcol=c(2,2)) plot(x <- sort(rnorm(7)), type = "s", main = "", ylab="", xlab="") plot(x <- sort(rnorm(27)), type = "s", main = "", ylab="", xlab="") plot(x <- sort(rnorm(47)), type =

I am trying to make a nice 2x1 plot and add a timestamp with comment. The pstamp function from Hmisc works nicely when mfcol=c(1,1), but when mfcol=c(2,1), the stamp winds up in the wrong place: > require('Hmisc') > opar <- par(mfcol=c(2,1)) > plot(1:10) > title(main="MAIN Title") > plot(1:20) > title(main="Another Title") > pstamp("normal

Dear R users, I'm making multiple plots within the same pdf page (par(mfcol = c(5,1)), and want a legend for this at the bottom of all the plots. From previous mails it has been suggested to use par(xpd=TRUE), increase the margin at the last plot, and then draw the legend. However, when I do this, the last plot gets smaller with the same amount I increase the margin with. The problem seems to

Hi r-users, I want to use the sn package but I got the following message: > install.packages(repos=NULL,pkgs="c:\\Tinn-R\\sn_0.4-12.zip") Warning: package 'sn' is in use and will not be installed updating HTML package descriptions I did tried to do it a few times but it gives the same message.  ________________________________ From:

I''m currently developing a photo gallery website with Rails. Each photo can be commented upon. What I''d like to do is, once the user posts a comment, use AJAX to submit the comment and then automatically update the page with the comment the user just submitted. I also don''t want to use Prototype or the built in AJAX that comes with Rails... it''s too fat

Hi there I'm sure this question has been raised a number of times before, but unfortunately I do not have direct access to the archives I am about to roll out Asterisk to a few companies and would like to hear your experiences about the various handsets/phones that are Asterisk compatible I am primarily looking for 2 options, the first being a cheaper model which will provide reliability

Is there a way to achieve lbl=c("a", "b", "c", "d") par(mfrow=c(2,2), ann=FALSE) for (t in 1:4){ plot(seq(from=1,to=2*pi,length=100), sin(t*seq(from=1,to=2*pi,length=100)), type="l") title(main=paste("(", lbl[t], ")", sep="")) } without having to use an object like 'lbl'? More generally: is it possible
