Dear list, Can somebody tell me how to invoke user-defined functions from script files during run-time? Basically I have (almost) one function per script file. I am thinking of something like #include in C++ import in Java/Python use in Perl No, I don't need my functions every time R is started. Neither I am thinking about writing building my functions into packages. I just

Hi all, I have a large data.frame, 1530 observation with 6 columns. I want to merge a 7th column, a transformation of the response variable (hospital admissions), namely trans<-sqrt(copd$admissions+0.25) trans<-data.frame(trans) And now when I do copd2<-merge(copd,trans) (copd being my original data.frame), R either crashes or is taking an extremely long time to do the computation. I

Hi, I was wondering whether there was an easy way to change the attributes of all elements in a data.frame (rather than looping through elements)? Specifically, I would like to set the "dim" attributes to NULL Thanks for any help, Jarrod -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Dear All, I would like to be able to plot histograms/densities on a semi-log or log-log scale.

Greetings helpRs -- I would like to use plot() to plot two cumulative distribution curves so that a user of the plot can compare the distributions of the two variables. The following code draws two distributions separately, but I cannot find the instruction necessary to add a second cumulative distribution to the first one. Any suggestion would be very welcome. x1 <-

All, I think this is pretty basic but I couldn't find the answer in any source. I have just built my own R for Linux (amd 64). It runs well, but R thinks that it only has 80 characters or so of screen width. I log on with Putty to the box and can stretch it as large as I want. Is there a simple way to tell R to use more screen width when displaying? From whatami: OS RELEASE :

Is there a good and concise way of making simultaneous plots that are identical, but directed to different devices? I'm writing an R-script that produces a pdf file. I would really like to check visually whether the pdf file shows what I expect. So I would like the same commands to produce a plot on screen. At the moment I'm using cut-and-paste, which is not ideal because any corrections

Dear all, I was trying to rotate a plot using R. I tried most of the examples offered here in this forum, but for some reason it is not working for a Scatterplot or in my case: plot (x,y). With a histogram I had no problems. Is it not possible to rotate a simple plot? Thanks a lot, Michael [[alternative HTML version deleted]]

Hi all I would like to know a bit more about illustrating an a4 page within R. Finally I would like to have a pdf with multiple pages containing some statistics. I'm already able to produce a pdf, containing a plot in the center of one a4 page. As a next step I would like to set a title on top of this a4 page (maybe with absolute positions, if not possible to set it relative?). The plots then
