Hi, everyone, I was trying to sort a data frame by two columns, one increasing, the other decreasing and got an error. "Error in FUN(left) : invalid argument to unary operator", The command is "BA[order(BA[1],-BA[2]),]". BA is the data frame. It was working if I used increasing on both columns. Why the decreasing symbol "-" is not working here? Thanks. -- Jun Shen PhD PK/PD Scientist BioPharma Services Millipore Corporation 15 Research Park Dr. St Charles, MO 63304 Direct:...

We had to move our dovecot from one server to another and used rsync to move the mail but it took us some time.. In our log at the new server, we are getting a lot of these..: 2010/10/08 23:28:23 imap(emailadr): Error: Index /opt/vmail/ba-avis.no/bpe/mail/.Nettforum/dovecot.index: Lost log for seq=22 offset=25248 2010/10/08 23:28:23 imap(emailadr): Warning: fscking index file /opt/vmail/ba-avis.no/bpe/mail/.Nettforum/dovecot.index 2010/10/08 23:28:23 imap(emailadr): Error: /opt/vmail/ba-avis.no/bpe/mail/.Nettforum/dovecot.index log...

Hello everybody, In am trying to analyse a BACI experiment and I really want to do it with R (which I find really exciting). So, before moving on I though it would be a good idea to repeat some known experiments which are quite similar to my own. I tried to reproduce 2 published examples but without much success. The first one in particul...

...create a new variable b - in "temp" - that matches values from b in "myref" to values in c. If you look at the resulting data frame (temp - at the bottom), you'll notice that rows 19-24 are incorrect. How could one fix it? Thanks a lot! # my reference data frame: a=c("ba ba","ca ca","da da", "lake lake, a", "lake lake, b","lake of","lama ca, a","lama ca, b","ma ma") b=c("ba ba","ca ca","OTHER", "lake lake, a", "lake lake, b","l...

OK. About the error it’s a long story, so it’s probably better to pin some source code here. Below is a piece of code related to my problem, clipped from lib/Transforms/Utils/ValueMapper.cpp. I was wondering what “materialized” means here. Value *Mapper::mapBlockAddress(const BlockAddress &BA) { Function *F = cast<Function>(mapValue(BA....

Hello, I am performing a BACI analysis with ANOVA using the following glm: fit1<-glm(log(Cucs_m+1)~(BA*Otter)+BA+Otter+ID+Primary, data=b1) The summary(aov(fit1)) shows significance in the interaction; however, now I would like to determine what combinations of BA and Otter are significantly different (each factor has t...

Hi Aki & Dovecot team, Just continuing with the previous discussion "Migration from one server to 2 new servers". Hi, I have tried the same way as per your suggestion.

Hi to all the people, I'm working with abundance data of some species, but containing too zero values, and the factors are the ones typical in a BACI experiment (Before-and-After-Control-Impact). Thus, these are two fixed factors. As the data does not holds the normality and homogeneity of variances assumptions of clasiccal ANOVA, I'm trying to fit a zero-altered model using the MCMC glmm library. I've two questions: 1.- how I can inc...

Greetings, I am recoding a dummy variable (coded 1,0) so that 0 = 2. I am using the line sciach$dummyba[sciach$ba==0] <- 2 I notice that it creates a new column dummyba, with 0 coded as 2 but with 1's now coded as NA. Is there a simple way around this in the line I am using, or do I need to have an additional line sciach$dummyba[sciach$ba==1] <- 1 Thanks in advance. David
