Suppose you're reading data from a file in which the column names contain underscore characters. Example: ------ start of file ----- pos_x pos_y 1.0 0.0 2.0 1.0 ------ end of file ------- Using read.table, I can read this file just fine: > data <- read.table (file="data", head=T) > data pos_x pos_y 1 1 0 2 2 1 > However, I can't

1) Is it possible to erase data points, legends, and/or text from an R plot? 2) What's the best way to find the closest data point to what locator() returns? For more background and some context on these questions, read on... In using R interactively, I am displaying further details about a specific data point when the user clicks on the plot point. Here's a simple example: #

Task: To generate HTML output from R Details: I am trying to serve up HTML output from R. That is analyses or table of data from R saved as HTML output with formatted tables etc. This file is then called in a CGI script to output to user browser. The CGI script inspired by Mark J. Ray reads the HTML output, formats the header and footer and any graphic output if necessary. My question is: Has

Has anyone successfully installed ESS on Win95? I have emacs version 19.34.6 and R version 0.63.3. The ESS README and Makefiles seem pretty Unix-specific. -- Terry J.

Is there a way to read a file one line at a time? My file is potentially very large (multiple gigabytes) so I'd like to read and process one line at a time. The only choices I see are: 1) Direct the file to standard input and use readline(), but then I have to parse the data columns myself. 2) Call scan() with nlines=1 over and over again, incrementing skip, but I suspect that it will

Has anyone succeeded in using HDF5 in R? Using Solaris R version 0.64.0: 1) R was configured in this way: cd /home/westley/R/R-0.64.0 setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:/home/westley/HDF/lib ./configure \ --prefix=/home/westley/R \ --with-g77=/usr/calspan/gnu/bin/g77 \ --x-lib=/usr/openwin/lib \ --with-hdf5-libs=/home/westley/HDF/lib 2) But, when I attempt to

I'm an R newbie, so please forgive if this question has been asked and answered many times before on this mailing list. I can't find anything in the manual (Notes or R), the FAQ or on CRAN, so... Has anyone implemented an interface so R can read NCSA's HDF? -- Terry J. Westley, Principal Engineer Veridian Engineering, Calspan Operations P.O. Box 400, Buffalo, NY 14225 twestley at

I need to build R (we're currently at R version 0.64.0) for Solaris 2.5.1 on SunSPARC without using the libF77.so and libsunmath.so shared libraries. I'd like to use statically linked libraries instead. Nothing I have tried has worked as measured by executing the command "ldd R.binary" to see whether it references the shared libraries or not. This is what I've tried: 1)

In version 0.63.0 for Win95, I can use text() to write into the left margin (to the left of the axis) as follows: > plot(0:10,0:10,pch="+") > text(c(1,0.5,0,-0.5,-1),1,"O") I see 5 "O" symbols at the expected position, two of which are left of the left axis. However, in version 0.64.0 for Solaris 2.5.1 on a Sparc/Ultra2, I only see three "O"

Dear developers, I wonder would you consider making a save to a graphics file format (as opposed to ps)? What prompts this is that we have just finished my wife's thesis using R heavily for stats and graphs. The combination of latex, bibtex and R generated .eps worked a treat and we were very pleased with both the final outcome and the efficiency of gernerating it, especially when all the

I hope this is merely a FAQ, and not an AFAQ (annoyingly....). I'm a SAS programmer, with several years' experience of the system, evaluating alternatives. See the SAS for Linux website (URL in sig) for more info. I'm exploring R's capabilities and limitations. I'd be very interested in having a deeper understanding of it capacity and performance limitations in dealing with

I am trying to use the Windows version of R to do the following: - Have a Delphi front-end which gets the user input - Delphi will produce a R script, do a system call to R to calculate the statistics. Is there a better way? Maybe a library one can use in Delphi or Visual C? - How do one see a graph? A graph is plotted in a window which IMMEDIATELY closes afterwords so that one can't

Is there a way to measure the length of a character string as text() or mtext() would display it? Not in characters, but in inches or user coordinates. I'm displaying a hierarchical list in the left margin. I'd like to determine the length of the labels so that I can resize the plot so the labels don't spill over into the plot area. Like this:

I've a plot which puts some text and lines in a wider than normal left margin (using xpd=T). When I use dev.print() to capture the plot to postscript, it faithfully duplicates the plot except for the graphics in the left margin. I can't duplicate this effect in a simple plot such as plot(runif(10)), so I can't give you sample code. Any idea what I'm doing wrong? R version

When running R in batch mode, I would like to detect certain errors and prevent them from terminating the script. Specifically, when I read in a file with read.table() and the file is empty, the script terminates. There are occasions when an empty file is OK, so I'd like to continue running. How can I catch such errors? -- Terry J. Westley, Software Systems Engineering Supervisor Veridian

I have a WLS regression with 1 dependent variable and 3 independent variables. I wish to constrain the predicted values (the fitted values) so that they are greater than zero (i.e. they are positive). I do not know how to impose this constraint in R. Please respond if you have any suggestions. There are some previous postings about constraining the coefficients, but this won't accomplish
