similar to: Subset of a subset?

(See DAAG book, p. 173, ex. 3) I'm a new user of R, and I'm following the DAAG text. I want to create a subset of the races2000 data frame, but get errors because of a mismatch of values in some columns: > library(DAAG) > attach(races2000) > hills2000 <- races2000[races2000$type == 'hill'] Error in as.matrix.data.frame(x) : dim<- : dims [product 770] do not

Here's the details and some debugging I did for starters, but I have no idea where to proceed from here. Help please? Command to reproduce should be in the strace output below. -Dan P.S. Sorry for sending this a few times; I think only one will make it through to the list since I wasn't subscribed initially. $ rsync --version rsync version 3.1.0 protocol version 31 Copyright (C)

You've omitted a comma. races2000 is a data frame, which for purposes of extracting rows behaves like a 2-dimenional object. The following works fine: hills2000 <- races2000[races2000$type == 'hill', ] Additionally, you might like to ponder > type <- races2000[names(races2000)=="type"] > type[1:4] Error in "[.data.frame"(type, 1:4) :

Hi, Rowland, and thanks for the reply. The PDC OS is Slackware 13. The BDC OS is Slackware 14. The choice to use Samba 4.0 was merely due to its inclusion on the Slackware 14 distro. I'll worry about upgrading that once I have the migration complete. I will post the two machine's respective smb.conf's later today. -- View this message in context:

As promised, I'm posting the smb.conf files for the two servers in question. One minor correction I should offer is that the new SAMBA server will be version 4.1, not 4.0. Following is SMB.CONF for the current PDC, which is Samba 3.3.4 on Slackware 13. I've omitted all share definitions to allow focus more on the configuration side. Actual server/domain names have been omitted.

I would like to Build R-2.5.1 on OpenSUSE 10.2 using the SunStudio 12 compilers(http://developers.sun.com/sunstudio/index.jsp) R builds and passes make check fine without optimising. However, when I try to compile with optimisation turned on (-fast) the build gets stuck in an infinite loop at the following point: Sun_Studio/sunstudio12/bin/cc -m64 -shared -Kpic -m64 -fPIC -o grDevices.so

Hi R user,I am struggling to figure out on how I can calculate the average from the two tables in R. Any one can help me? really your help would be grateful- I am spending so much time to figure it out. It should not be so hard, I think. I have very big data but I have created a hypothetical data for simplification. for example I have : table 1 table 1: species occurance data

Hi all, I need all your help on this. I have the next part of code:............e1=x1-mean(x1)e2=x2-mean(x2)n1=length(x1)n2=length(x2N=(n1 + n2)nu2=sum( c( ( x1 -mean(x1) )^2 , ( x2-mean(x2) )^2 ) )/Nss=c(e1,e2) b3= N*sum(ss^4)/ (sum( ss^2)^2)............what do lines 6-8 (mathematical notation)?Also the, what means part?............for(j in 1:B){ ss11=sample(x1, n1, replace=TRUE) ss12=sample(x2,

Dear List, somebody knows, if the following operation can be done in an easier way? The data rows which should be read into R look like that: 4547;1970.01.01 00:00-1970.01.01 01:00; noData Unitil now we are doing this procedure: 1. Dividing columns which are separated by ";" => temp <- read.table(file ,sep=';', na.strings='noData', strip.white=TRUE) =>

Dear all, We are trying to clean multiple realizations of a pattern. Erroneous NODATA and spurious DATA occur in the realizations. As we have to do a 1000 realizations for many patterns, efficiency of the code is important. We need to correct the realizations with a 'mask' pattern of DATA/NODATA. We think an ifelse should do the job. Spurious DATA will be simply removed using the

Hi if I try to import a raster layer which consists only of NULL values from grass by using the readRAST6, I get an error message: > readRAST6("HSericea_seedsDisperse_2007") ERROR: Invalid value for null (integers only) Error in readBinGrid(rtmpfl11, colname = vname[i], proj4string = p4, integer = to_int) : no such file:

If I want to do a join based on *two* matching fields in two data frames, can merge() handle this? It appears to only handle a single matching column -- do I need to make a "metacolumn" or is there some way to do this? E.g.: Dataframe 1 contains columns A,B,C and Dataframe 2 contains A,B,D I want an output A,B,C,D which places C and D together if A and B match (otherwise, make two

Hello, I discovered SAGA, an interesting free GIS, a few days ago and now, I would like to use it from within R 2.6.2 using the RSAGA package. I read the documentation for this package and thought that I understood it correctly for trying to call some of the SAGA modules. For getting the information on the usage of and arguments required by the SAGA command line "Import Binary Raw

Hello. We're using dovecot with mysql for authentication, with postfixadmin for the admin web interface. We are moving users from passwd file usernames to email at domain style logins. Is there a better way to allow both sets of usernames (old and new) to work with dovecot than by adding extra copies of rows to the mailboxes table and changing the username? i.e. does dovecot support some
