similar to: combining mathematical notation and value substitution

Dear R-users, I'm trying to add a title on a plot with both mathematical notation and values substitution. I read the documentation and search the mailing list but I was not able to solve my problem. Actually, there is a message by Uwe Ligges on June 2003 which addresses a question very close to mine, but the code provided doesn't work. The code is the following: # I add this to let you

Dear People, In a qqplot I am doing, I get lines/points that are very thick. I've tried setting the lwd variable to 0.1, but it doesn't seem to have any effect. Also, I have set the value of lty to dashed, but I still get dots. The command looks like qqplot(cdf.inv(seq(0,1,length=size),theta,pos,len),empmargdistvec(len,theta,pos,size), xlim=c(-theta,theta), ylim=c(-theta,theta),

Dear People, I hope someone can help me with this. I have a function (density) which I am trying to plot using curve. I am calling mg.hist(3,2,1), and getting the following errors. Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ In addition: There were 50 or more warnings (use warnings() to see the first 50) > warnings() 1: longer object length is not a multiple of

Dear People, I have a data set of data x from a probability distribution, and I have a function, mydensity, of the pdf of that distribution. I'm asking for help in superimposing the histogram of x and the plot of mydensity. In the function below, I call truehist and curve, but these are plotted in different figures. I'd like them to be plotted on the same figure, and to use common

Dear People, I just went back to an old piece of C code. On trying to compile it with the R math standalone C library I got the following error. Can anyone enlighten me what I am doing wrong, if anything? C file (rr-sa.c) follows. I'm on Debian sarge. I'm running R version 1.8.1. Gcc is version 3.3.1. Thanks in advance. Faheem.

Dear People, I am sure I am missing something obvious as usual, but in the following graph I can't plot ylab. Ignoring unimportant details, I am plotting one instance of truehist() and one instance of curve() on the same graph. Truehist() won't let me pass the ylab argument. It gives me the error Error in plot.default(xlim, c(0, ymax), type = "n", xlab = xlab, ylab =

Dear People, Consider the following fragment of R code choose <- function(n,r) { if( is.integer(n) && is.integer(r) && n > 0 && r >= 0 ) { .C("choose",as.double(n),as.double(r),comb = double(1))$comb } else stop("n must be a positive integer and r a non-negative integer.") } This is a practice function (n choose r), which I

Hi, Is there a way to check whether a file is empty in R. I did the customary searches, but did not find anything. Please cc me on any reply. Thanks, Faheem.

Hi, Consider the following > x = c(1,2) > y = c(3,4) > d = data.frame(cbind(x,y)) > d$x [1] 1 2 > d$"x" [1] 1 2 > > foo = function(val) + { + return(d$val) + } > > bar = function() + { + return(d$"x") + } > > foo("x") NULL > bar() [1] 1 2 I'm a little surprised that R accepts both the form d$x and d$"x", but

Dear People, I am trying to include a barplot (see code below), in a latex document. However, the plot appears in totally the wrong position. I know this is not an R question as such, but the eps file is produced by R and I thought that perhaps other people had had similar problems and could give me pointers. Am I doing anything obviously wrong? Sincerely, Faheem Mitha. PS.

Dear R people, The header practically says it all. I was wanting to include r code in a Latex file. Since R code using{ and }, which are interpreted by Latex as control characters, I would expect it to get upset. I believe that \{ would probably print as {, but I hoping I don't have to go through the code and add lots of \. I would rather use some global commannd, along the lines of

Dear People, I have been trying to perform concatenation operations on lists without success. Consider the following example. > x <- runif(2) > y <- runif(2) > z <- runif(2) > xy <- list(x,y) > xyz <- list(x,y,z) I want to have a function foo such that foo(xy,z) is the same as xyz. This appears not to be as easy as I thought, though there must be a way. For example

Dear People, After considerable effort, I managed to install gcc-3.0 on my Debian system. However, Debian keeps gcc-2.95 around as the default compiler, and gcc, g++ point to the 2.95 version. The 3.0 versions need to be explicitly invoked as gcc-3.0, g++-3.0 etc. How can I get R CMD SHLIB to invoke gcc-3.0 instead of gcc and g++-3.0 instead of g++? I would like this to be done by default but

I have the following question, which is elementary but I am unable to answer. In a for(i=10) loop, I am trying to represent the 10 1-dimensional vectors l1, l2,... l10 by some expression that will run through these values. ie. soppose I want to add l1 + ... + l10 I could go x <- 0 for(i in 1:10){ x <- x+ l(i)} This should return x to be the sum of the 10 li's for i from 1 to 10

Dear R people, I have the following simple bit of code to make a plot. I want to suppress tick marks on the axes of the plot. I've been trying everything I can think of to do so, but have been unsuccessful. Can you help me? If you reply, please cc me, I'm not currently subscribed to the list. Thanks in advance. Sincerely, Faheem Mitha. num <- 1:i inc

Dear rsync people, I have just started using rsync for backups. I have had a couple of issues. Note I'm trying to use rsync as user using ssh between two machines both running Debian GNU/Linux potato (2.2r3). The local machine is currently running 2.4.6-1 and the remote 2.3.2-1.2. 1) When I run rsync with the vv option, stuff scrolls of my screen faster than I can read it. I was wondering if

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

Dear R People, I getting some curious behaviour with the integrate function. Consider the function foo <- function(x) { if(x==0) 4 else 0 } I get the error > integrate(foo,0,1) Error in integrate(foo, 0, 1) : evaluation of function gave a result of wrong length But now consider foo <- function(x) { ifelse(x==0,4,0) } > integrate(foo,0,1) 0 with absolute error

Dear R People, I want to include a barplot corresponding to a simple discrete probability distribution in a LaTeX document. I decided to use the pictex driver. After a certain amount of messing about, I came up the stuff below. It does not look too bad, however, there is one very obvious piece of weirdness, ie. the y axis terminates at 0.1 and does not extend down further. I tried to adjust this
