similar to: length() misbehaving?

With the problem below, I've discoved that n95trt<-length(byyr$cnd95[byyr$cnd95=="tr"&!is.na(byyr$cnd95)]) does give me the correct count for the number of "tr" entries. (The same behavior occurs for the "c" level of the cnd95 factor.) It appears that byyr$cnd95=="tr" is finding both "tr" AND NA entries. Is this a bug, or is it to be

I've been successfully using a dll via dyn.load() with R1.6.0 for Windows, but when I try it under R1.6.1 it manages to crash the program completely. Has there been a change in how R1.6.1 handles dynamic loading? I couldn't spot any such changes in the documentation. This problem occurred on two different machines, and both run the code under R1.6.0 without a problem. Rob Hyndman

Hello. I have an R program that calls gawk (GNU Awk 3.06 for Windows) from within pipe() to preprocess a large file before it is read into a data frame with read.table(). I've recently upgraded from Win98SE to WinXP, and have also upgraded from R1.5.0 to R1.6.1 over the past month or so. This program worked before the upgrade(s), but now fails. I observe the following sort of behavior with

I can't get identify to work, using R 2.0.1 under windows xp pro, service pack 2. Here's what I enter, and the result: > plot((our.frame2$c1),(our.frame2$c9)) # Produces desired plot > identify(our.frame2$c1) # Plot comes to forefront, so I select a point warning: no point with 0.25 inches numeric(0) Is my call to identify correct?

I'm using R in a statistics class, and when I project the console, the font is smaller than ideal. I've checked the faq's, the manual, and the help system as best I can, and I don't see how to change the font size. Can it be changed from within a session, or will I have to ask the folks who installed the program on the server I use in classes to set it (assuming that can be

I'm using R 2.0.1 in a class I teach, with most students working under windows XP. We have a data frame with the first column containing the factor "site," and five water-quality variables at each site. As one part of exploring these data, I'd like the students to run by(ourdata,site,pairs). When I try that, however, the pairs plots for the first 10 sites scroll past, and

After entering ?library(rpart)?, I tried to plot an existing rpart tree, and got this error message: Error: couldn't find function "plot.rpart". However, ??plot.rpart? does bring up the help for the function. The same things occur for text.rpart, although print(my.tree) does work. So, I tried to re-install rpart using Packages | Install from CRAN, but then I get this

Hi, there might be a bug in read.delim (also read.table) in R.1.6.2. I included the correct input done in R1.6.1 first, then the wrong input in R1.6.2. The discrepancies are highlighted in red.

I've looked every way I can think of for help on trellis.datasets, but nothing comes up for me. Please help me find information on what is included, and how to get at those data. Thanks. Dave Parkhurst

Hello. For building REmbeddedPostgres in Omegat project(http://www.omegahat.org/RSPostgres/) requiring PostgresSQL's libs, I've tried to build R1.6.1 on Cygwin following the instruction of http://www.stats.ox.ac.uk/pub/Rtools/ since full-spec PostgresSQL running on Windows can run only on Cygwin environment, However I've got following error messages. make -C front-ends Rpwd

Greetings: I am trying to work with spdep (everything is "brand new" downloaded this morning). OS = Windows 2000 (also up to date). The code I am using follows: #example gal.county=read.geoda("lnpilnd.GAL", row.names=NULL, skip=0) summary.nb(gal.county) Error in summary.nb(gal.county) : Not a neighbours list #end The gal file works just fine in GeoDa (also up to date).

Greetings: I would like to make a table with descriptive statistics for a data.frame. I guess the question is how can I put together, in a table, the results from, say: apply(df, 2, mean, na.rm =T) apply(df, 2, median, na.rm =T) .......

Dear friends - using windows xp and R1.6.1 when doing x <- 12 as.character(x) [1] "12" plot(1,2,pch=as.character(x)) the interesting point is marked with: 1 whereas I would like to see 12. In par() is specified under pch: Either an integer specifying a symbol or a single character to be used as the default in plotting points How is that overridden ? Best wishes Troels --------------

In trying to execute this line in R (Version 1.7.1 (2003-06-16), under windows XP pro), with the randomForest library (about two weeks old) loaded, the program crashed: bost4rf <- rfImpute(TargetDensity~.,data=bost4rf0) Specifically, an XP dialog box popped up, saying ?R for windows GUI front-end has encountered a problem and needs to close.? That was the dialog saying asking whether I

The help page for randomForest shows na.action=na.fail as a parameter, and does not describe other possibilities for na.action. I have a regression problem, with about 1000 rows in my data frame, and with an NA in occasional predictor variables, in about 5% of rows. I would like to have all rows included in the analysis, to the extent possible. (That seems to be possible in rpart, for example.)

I'm using R 1.8.0 under windows XP. I can't get certain of the graphics devices set up. For example, when I copy this line directly from the "postscript" help screen, I get the error messages that follow it: > postscript("foo.ps") Error in PS(file, old$paper, old$family, old$encoding, old$bg, old$fg, : unable to start device PostScript In addition:

I'm using R 2.0.1 in windows XP (and am not currently subscribed to this mailing list). I have a USGS dataset, a text file with fixed width fields, that includes dates as 6-digit integers in the form yrmoda. I could either read them that way, or with yr, mo, and da as separate integers. In either case, I'd like to convert them to a form will allow plotting other "y"

Microsoft Windows R users, I am operating Windows 2000 (build2195) with R1.7. It may be pertinent that I am using a dual head screen with the initial RGui filing the entire area of both screens. When starting R I use the .First() function to add menu items to the RGui interface using winMenuAdd() and winMenuAddItem(). The menus do not display until the RGui window is physically manipulated in

I am not sure if this is a bug in ActiveRecord or is this the intended behavior. If it is then it does not make sense to me. In a nutshell: If you change an aggregate object attribute created via composed_of method (see Agile Web Development - Second Edition Chapter 17 page 313 onwards) and then save the model, the change to the model (composite attribute specifically) will not be saved UNLESS
