dum is a simple data frame transferred to Splus using the dump() command in Splus and the source() in R. All fields are numeric. There are no missing data. The data frame looks like it is should: > apply(dum,2,mode) yrcl sland s02 s234 "numeric" "numeric" "numeric" "numeric" > apply(dum,2,is.vector) yrcl sland s02 s234

Here is a simple example of what I would like to do: Given a data frame foo with variables x and fn. Suppose fn is a vector of characters which correspond to names of previously defined functions which have only one argument. I would like a vector returned where fn is applied to x foo <- data.frame(x=c(2,5,7), fn = letters[c(6,7,6)]) foo$fn <- as.character(foo$fn) "f" <-

I am in the process of setting up R1.3.1 on a new computer running windows 2000. I am having problems running the PFE text editor simultaneously within R for editing functions and outside R for editing ordinary text files. The PFE editor behaves as I expected, if it is opened in R AND but no other PFE window is open outside R. Similarly, it also works fine if I am editing a text file outside

I am comparing the Splus and R fits of a simple glm. In the following, foo is generated from rbinom with size = 20 p = 0.5. The coefficients (and SE's0 of the fitted models are the same, but the estimated deviances are quite different. Could someone please tell me why they are so different? I am using R version 1.3.1 and Splus 2000 release 3 on windows 2000. ++++++++++++++++++++++ foo

Could someone suggest a mail reader that will parse a digest from r-help into separate messages? Preferably, this reader would allow replies or forwards of separate messages. I use pine on a Sun running SunOS 5.7. If there were an add-on to pine that would accomplish this task, that would be even better. Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

I've been trying to download from CRAN the floppy versions of the R source files: R-release-1.tar.gz, R-release-2.tar.gz I tried the servers in Seattle, Madison, and the Vienna Technical University. In each case, the file(s) were unavailable. Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E. York National Marine Mammal Laboratory Seattle WA 98115-0070 USA e-mail: anne.york at noaa.gov

Dear R-help, I find the example() function is extremely useful in many ways. However, there's a minor inconvenience: for long examples, it leaves lots of objects in the workspace. While it's sometimes useful to have the objects around for further exploration, other times they just add to the clutter. Does anyone have a good way of cleaning up afterward? If not, would R core consider

The help for the round function states: round rounds the values in its first argument to the specified number of decimal places (default 0). Note that for rounding off a 5, the IEEE standard is used, ``go to the even digit''. Therefore round(0.5) is 0 and round(-1.5) is -2. Could someone provide a reference for this standard? Thanks, Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

Dear R Experts, Is there a way in R to add an error bar (say in the y direction) for each data point?

Is there a way to put a legend on an xyplot -- eg, something akin to the key function? Or, is there a way to get the R legend function to work on a lattice plot? To the people who have done the work on lattice and grid: Thanks for making lattice. I'm finding it very useful. Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

The standard errors produced by predict.glm with type = "response" seem wrong. Here is an example using R 1.2 windows version along with the same problem in Splus. The standard errors for type = "link" are the same in both systems. R1.2> set.seed(10) R1.2> ytest <- 100*.95^(0:9) + rnorm(10,sd = 5) R1.2> ytest [1] 103.96964 97.60590 88.43220 85.90504

Dear list, I am facing the following problem with the legend of a plot that display the mean and variance of a measurement y as a function of x, the mean being represented by a dot and the variance by a vertical line. My problem is that I am unable to display the symbol (dot + vertical line) in the legend. any help is welcome, thanks marco --

Points, axes and axes labels on graphs printed from R are very light- almost unreadable. I am using the gui interface on the windows version to print the plot on the screen to an HP 8000 set as a postscript printer or PCL printer; the postscript output is light and the PCL output is very light. If I specify lwd =2 in the plot command, the lines are readable, but the points (open circles, in

Hi I'm exporting some graphs from R to M$Word. I used png, jpeg and bmp and the quality is poor when comparing with the postscript. What is the best way to export a chart to be included in a M$Word file ? Thanks EJ

Hi, I'm looking to create a few basic world maps in R (for Windows). A while back someone asked for the same thing and was referred to the (*.tar) files at: ftp://ftp.mcs.vuw.ac.nz/pub/statistics/map/ which I downloaded. However, I am unable to install them, and clearly I'm not doing something properly (I'm your basic moron when it comes to installation, so please understand).

Hello, I wonder if someone could send me suggestions on how to solve the following problem: I have a vector of an arbitrary size (ex. data<-c(10,10,11,10,12,11,10,12,11,11,10,11)) and use the table function, which gives the following result 10 11 12 5 5 2 that''s fine, but what I would like to do now is: construct new classes based on the number of classes from table, 10

Thank you very much for your help, your fuction runs on R without any change, and the results are the same that your obtain with Splus, but there still a small difference. In SAS W=0.960439 With your shapiro.wilk.test W=0.9606107 But the p-values are almost the same. Thank you very much for your help. > Here is a function for the Shapiro-wilk test that I obtained from StatLib. > Using

Hello, I'm looking for a way to plot different data series on one graph. I have a series of hourly rainfall and quarterly flow measurements (i.e. 4 times an hour) of a catchment. The rainfall should be plotted in bars, the flow as a line. Both on the same X axe (time) but with different Y axes. The problem is the plot() function does not support add=TRUE... Furthermore I'm not sure
