I need to replace <NA> occurrences in multiple columns in a data.frame with "000/000" how do I achieve this? Thanks Nevil Amos

...I end up with all rows/ columns that are not NA - e.g. 1 2 3 4 5 7 8 9 1 0 2 1 2 1 1 2 1 2 2 0 1 2 1 1 2 1 3 1 1 0 2 1 1 2 1 4 2 2 2 0 1 1 2 1 5 1 1 1 1 0 1 2 1 7 1 1 1 1 1 0 2 1 8 2 2 2 2 2 2 0 1 9 1 1 1 1 1 1 1 0 if i use na omit I lose rows 1,2,6, and 9 which is not what I want. thanks -- Nevil Amos Molecular Ecology Research Group Australian Centre for Biodiversity Monash University CLAYTON VIC 3800 Australia [[alternative HTML version deleted]]

Is there a fuction that will allow me to retrun the filename for a script from within that script. fir instance If I have a script "myscript.r": FileName<-unknown.fucntion() print(FileName) and run it source("myscript.r") will return "myscript.r" Thanks Nevil Amos [[alternative HTML version deleted]]

...<-' is not an exported object from 'namespace:raster' I have also tried just using levels(r) and putting raster as a depends rather than an import in the DESCRIPTION file for the package, this does not solve the error. Any suggestions on how to overcome the problem? many thanks Nevil Amos [[alternative HTML version deleted]]

...measurement/observer error, compared to difference between individuals error I have looked at doing this with icc{irr} or using an anova approach, but I am unclear how to acheive this given that there is a nested structure- the value varies between wavelengths within individuals.

is there a way to reduce the size of pdf files in R: ? compression? lower dpi ? or some other option?

...h test is the appropriate one to use ( I believe capscale since it is "similar to distance-based redundancy analysis (Legendre & Anderson 1999)") and whether this test is indeed equivalent to the approach suggested by Legendre &Fortin, (Geffen et al used DISTLM). many thanks Nevil Amos ACB Monash University references (Geffen, E., M.

...RDONLY) To Fd = ensure_ep_open(dev, ep, 0, O_RDONLY | O_NONBLOCK) This just tells the read to return immediately if no data from usb rather than block. OS buffers device anyway. With this plus the information in the faqs I was able to achieve an operational system. Hope this is someway helps.
