Dear all, Can anybody tell me how to export a 3d figure made with the plot3d function? I'm careless about whether it's still interactive or not in another format, as long I can get it out of R.

I have found that the "schema.table" syntax used in Postgresql (and Oracle) does not work directly with RODBC. This works library(RODBC) con<-odbcConnect("mydb") d<-sqlQuery(con,"select * from meso.trees") However this does not. d<-sqlFetch(con,"meso.trees") Error in odbcTableExists(channel, sqtable) : ?meso.trees?: table not found on channel

Hello, My question is the following. Has anyone put together an "idiots" checklist of the steps needed to build a (small personal) package under Windows, or documented their own experiences of building packages under Windows? I ask this as last week there were some very interesting comments regarding the advantages of putting personally written functions together as a package

Does anyone have a way of producing solid shapes other than spheres in rgl? I am using rgl to produce a simple visualisation of a forest model results using "lollipops". Its just a bit of fun, but as many of the trees are pines I would like to depict their crowns as cones. If there is a solution I need it to work under windows. Here is the example. library(rgl) library(misc3d)

Could anyone help with what should be a simple task? I have data as a fixed format (fortran) table. I have no trouble getting it into R using read.table. Each column is separated by a space, including the first column that begins with a space, and aligned. It reads into R as if separated by tabs. However I want to manipulate two columns of data then write the results out into exactly the

I am running R on Ubuntu Heron. I recently updated to R 2.8.0 from the default (2.6) in the Ubuntu heron repository by adding deb http://cran.stat.sfu.ca/bin/linux/ubuntu hardy/ I updated all packages installed in /usr/lib/R/site-library and those in my home directory /home/duncan/R/i486-pc-linux-gnu-library/2.6 without obvious issues. I installed adehabitat and gpclib, which should be good

Hello, I've seen this question asked in the archives but no clear reply or solution provided. So, just to be sure it is not possible in R: Can I replace backslashes with slashes in a string ? I am writing a GUI for R with the Rpad library. I have a "browse" button for data loading and Windows return a path string with backslashes. I need to convert them into slashes to use the

Hi all, I have a Soekris net4801-50 board with OpenBSD 3.9 where I've configured a dhcp server and tested it with a regular PC connected directly via a crossover cable with success. The problem comes when I try to connect my IAXy device instead of the PC. I can see with 'tcpdump -nettti sis1' that the IAXy isn't sending any packets to the dhcp server. I thought my IAXy was bad

Hello, I'm running asterisk 1.0.7 on a kernel 2.4 linux box. I have my SIP users database on MySQL, also I'm running asterisk from static .conf files. What I want to get done is that after a pre defined period of time, my SIP users table must be converted to a .conf file. Perhaps with a script and cron entry. Please shed me some light on this. Thanks in advance. -- Juan Luis Moyano

Hello everyone, I hope this is a fair enough question, but I don’t have access to a copy of Bates and Pinheiro. It is probably quite obvious but the answer might be of general interest. If I fit a fixed effect with an added quadratic term and then do it as an orthogonal polynomial using maximum likelihood I get the expected result- they have the same logLik.

Hello. I am new to R. And, I want to perform a multiple nested anova on a large datasets (with 9448 observations). Under the helps from R-Sig-ecology mailing list, I have gained many progresses. But I still have some confusions. I want to ask for some helps here. my dataset("SeedL.txt") was not attached. Data are not sorted by factors. In this dataset, "SpecN"

Dear list members, I am new to R and to the R-help list. I am trying to perform a mixed-model analysis using the lmer() function. I have a problem with the output anova table when using the anova() function on the lmer output object: I only get the numerator d.f., the sum of squares and the mean squares, but not the denominator d.f., F statistics and P values. Below is a sample output, following

Hi, I'm having an issue with a soekris net4801 board and a S101i "IAXy" device. When I connect a successfully provisioned IAXy directly via a crossover cable into an ethernet port of the soekris, the link led turns on orange so i'ts 10Mb and the activity led blinks like if there is some action going on but when I try 'tcpdump -nettti sis1' I see nothing going on, no
