...I am relatively new to R and I am working through the code that is provided in the book Numerical Ecology with R and I have run across an error message that I can't seem to figure out. I am using the vegan, ade4, gclus and cluster packages. The code is as follows: # Ordered community table # Species are ordered by their weighted averages on site scores or <- vegemite(spe, spe.chwo) spe is the dataframe spe.chwo came from: spe.norm <- decostand(spe, "normalize") spe.ch <- vegdist(spe.norm, "euc") spe.ch.UPGMA <- hclust(spe.ch, method = "average&quo...

Hi all, >From a list of strings, I desire to filter out the followings: 1. Digits at the beginning of the strings 2. Character "SPE" following the digits (if it exists) 3. Any characters followed by hyphen The following produces the desired result, but would like to know whether this can be done more efficiently. Any suggestions would be much appreciated. dat <- c("2148 SPE MAR - CCC", "9843 SPE ANN -...

Dear R-gurus, Just supose I have a dara.frame that looks like myDF<-read.table(stdin(),head=T,sep=",") codID,namesp,k1,k2,k3,k4 1,spA,2,5,6,3 2,spB,4,5,4,6 3,spC,2,1,5,6 4,spC,5,4,3,2 5,spD,1,2,3,4 6,spE,2,4,3,1 I need to update the columns k1-k4 with the namesp, but considering the math between Kx and codID. My desired output must looks like: codID,namesp,k1,k2,k3,k4 1,spA,spB,spD,spE,spC 2,spB,... 3,spC,... 4,spC,... 5,spD,... 6,spE,... Any help are welcome. cheers milton [[alternative HT...

Hi, I am a new R user and am trying to construct a palaeoenvironmental transfer function (weighted averaging method) using the package rioja. I've managed to insert the two matrices (the species abundance and the environmental data) and have assigned them to the y and x values respectively. When I try and enter the 'WA' function though, I get an 'Error in FUN' message (see below for full values). Alas, I do not know what this means and have struggled to find similar pro...

Hello, I am using vegan to do an NMDS plot and I would like to suppress the labels for the loading vectors. Is this possible? Alternatively, how can I avoid overlap? Many thanks for the help. Example code: #perform NMDS using metaMDS() function spe.nmds<-metaMDS(data, distance='bray',k=2 , engine = "isoMDS", autotransform=F, trymax=1000) #calculate the loading (i.e., variable weights) on each NMDS axis vec.sp<-envfit(spe.nmds$points, data, perm=1000, choices=c(1:2)) #plot data in ordination ordiplot(spe.nmds, choice...

...I do not know if it will allow you to avoid the __attribute__ directives. Look at the TI subdirectory in the main tree for an example of how this is done. There is a bit of a hack for providing a private stack without changing the API. I do not think that there is any precedent for platform specific API changes, such as what you have proposed. It will take some work to move to the 1.2 branch, but with it comes two years of improvements in quality and processing and memory efficiency.

That reminds me that I've just moved lots of stuff around with the allocation functions. Can you check that the TI stuff still works with that? In the end, it'll probably make things easier for you now. For example, if you link statica...

...er split of codec and DSP stuff is done - probably it make sense to give codec part "stable" label, while maintaining DSP part as unstable? I think this will make things much clearer then they are now without many words being said. :) Well, it's a generic question, interesting to all Speex users, after all - do you want to maintain versions of codec and dsp parts separately or in conjunction? -- Regards, Alexander Chemeris.
