I installed jpeg package and tried to use kim<-readJPEG("kim.jpeg") to read in a jpeg file, but R gave me an error: Error in readJPEG("kim.jpeg") : unable to open kim.jpeg I already put "kim.jpeg" in Rstudio's default working directory: "E:\home work\Rstudio". So I don't think it's a problem caused by omitting the file's path. But I

Hi, I m working on R and read one image with russian font using readjpeg() function and write it on pdf (using grid). But russian text is not visible on pdf. How can i fix my pblm?

Hello, I''m trying to fit a linear mixed effects model of the form: lme(y ~ x * Sex * Year, random=x|subject) where Sex and Year are factors with two and three levels respectively. I want to compare the fixed effects for each level to the overall mean, but the default in R is to compare to the first level. This can be changed by adding the term -1 to the righthand side of the model

Hjalmar, I recall that many hardware decoders have a limit on the level that they can handle. At the very least, hardware encoders may only support a subset of the compression levels. As for the decoders, I cannot remember specifically whether they are all capable of decoding all compression levels (it certainly would be more convenient). My memory from discussions on this mailing list

Hi, Is there a function in R to calculate the nth root, similar to the MATLAB function NTHROOT()? Thanks, Martin Biuw [[alternative HTML version deleted]]

Hi all, I am using Match directive and internal-sftp to chroot sftp users into their directory. Connection and login works. I can change directories and put/get files. Also logging of the internal sftp-process works (created a /dev/log socket inside the chroot). As soon as I use the 'ls' command, nothing happens and the the process gets stuck. Listing files does work as soon as I remove

Hi all, I am using a 'tricked' Cox Hazard regression model for discrete choice habitat modelling. However, I'm having a hard time understanding the meaning of the first line the following part of the summary() output: Rsquare= 0.307 (max possible= 0.475 ) Likelihood ratio test= 91.8 on 12 df, p=2.23e-14 Wald test = 26.3 on 12 df, p=0.00977 Score (logrank) test = 58.6 on 12 df,

Hi all, I wish to do build discrete choice model to analyse habitat selection of wolverines. This can be done with a 'tricked' stratified Cox proportional hazard model. For each individual animal each selected position, and possible alternative non-used available positions are combined into strata. This means that one stratum contains a set of 1 used position and several positions which

Thanks to Roger Bivand, my problem was solved. binutils 2.14 was updatet to binutils 2.15, as indicated under.

I would also add that the "level" is only relevant to the reference encoder, as it is an alias to quickly set a number of parameters. Other encoders might make different choices. Also, I haven't looked in details at how the encoder works, but I think it is based on heuristics to decide which is the best compression method for a set of samples, and I'm not sure that it would give

Hi, Sorry if this is an obvious one, but is there a simple way to modify the lm function to test whether a slope coefficient is significantly different from 1 instead of different from 0?

Hello, Once again, I posted a message without a subject line. Sorry.... here is the question again. Is there a simple way to modify the circ.mean function in the CircStats package to include a vector of weights to obtain a weighted average angle? Thanks!

Hi, I change the dovecot.conf default_mail_env = mbox:/Mail/IMAP/%u/:INBOX=/var/mail/%u After I did the change, I restart dovecot with the hope that folder that I create will be stored in /Mail/IMAP/%u. Then I use Mozzila as my email client and change the IMAP server directory to ~nina/IMAP/ which is the link to /Mail/IMAP/nina/. But then I can not create folder anymore from Mozzila, or view

Dear all, The Norwegian Institute for Nature Research (NINA) seeks a post doc or Ph.D. candidate in mapping and valuation of ecosystem services from green infrastructure in Oslo. The candidate has preferably skills in Open Source GIS (OSGeo) and a M.Sc./Ph.D. in geomatics with an interest in urban ecosystem services, or a M.Sc./Ph.D. in nature management, landscape architecture, geography,

Hi I have a small problem, I'm new in using R, so I hope you can help me... I'm running a logistic regression model and want to do a nice plot. The plot I have made is done a plot with the command jitter: plot(jitter(overto$age[overto$sex=="F"]),jitter(overto$neg.pos[overto$sex=="F"]),xlab="age",ylab="neg and pos") my responsvariable is positive

I am running the aov function to determine the linear relationship between individual genes and a number of covariates in a micro-array data set. My aov function is working, but I have not been able to write a code to save these results in a matrix. I am using the following code or a slight variation of this code: for(i in 1(length(m[1,])-20) {tmp<- aov(m[,i]~treat, data=m)

Dear R-users, I intend to do a spatial analysis on the genetic structuring within a population. For this I had thought to prepare a kernel density estimate map showing the spatial distribution of individuals, while incorporating the genetic distances among individuals. I have a dataset of locations of N unique individuals (XY-coordinates) and an NxN matrix with the genetic distances given as a

Hello, I'm using the nls function and would like to increase the number of iterations. According to the documentation as well as other postings on R-help, I've tried to do this using the "control" argument: nls(y ~ SSfpl(x, A, B, xmid, scal), data=my.data, control=nls.control(maxiter=200)) but no matter how much I increase "maxiter", I get the following error
