I use R 2.15.2 on MacosX 10.8.2 I have a problem checking for a package that I want to submit in CRAN. When I check like that, no problem or warning are detected. system("R CMD check '[path]/phenology'") I create the .tar.gz package with that. The file phenology_3.43.tar.gz is generated. I can install the package and it works. system("R CMD build '[path]/phenology'") But if I check it using --as-cran as required by CRAN policy, system("R CMD check '[path]/p...

...9;m trying to select a model under PCA using independent contrasts. Since PICs need to be forced through the origin I've been using lmorigin for the original regression, but it doesn't appear that stepAIC recognizes it.

Hi, I am currently working with a data set which contains a list of julian dates of phenological (flowering, leaf growth etc.) I obtained a correlation matrix by simply using the cor function with the dataset cor(dataset,use="complete.obs") that gives me a correlation matrix but the correlations are somehow different from when I run individual correlations using the cor function and

Sometimes I also include another (reduced) figure, for example a reduced map indicating the geographic location of some sites, and or time-series of the phenology as shown by satellite imagery. Another example of adding ancillary information to an statistic graphic is adding field-collected information to a graphic that displays results from the analysis od remotely-sensed imagery. Thanks, Paul, for you work at improving the (many) R graphic capabilities....

does anybody have a suggestion as to how to use R to fit some date to a cosine function and then have some output statistics that will evaluate the fit? -- View this message in context: http://r.789695.n4.nabble.com/cosine-curve-fit-tp4650866.html Sent from the R help mailing list archive at Nabble.com.

well if you want to find the spectral density aka what frequencies explain most of the variance then I would suggest the spectral density. This can be implemented with spec.pgram(). This is conducted with the fast fourier transform algorithm. a<-ts(data, frequency = 1) #make the time series with 365readings/365days ?spec.pgram and you should be able to take it from here This will

Hello all- I have a question related to encoding. I'm using a seperate program which takes either 16 bit or 8 bit (flat binary files) as inputs (they are raster satellite imagery and the associated quality files), but can't handle both at the same time. Problem is the quality and the image come in different formats (quality- 8bit, image- 16bit). I need to switch the encoding on the
