Hi everybody, I am trying to make my mind about the use of R for Computational and Statistical Approaches to Genomics. I know this is a vaste field: this is the main reason why I am sending this message to this always useful list! Any key/entry point to this field will be extremely welcome! Please, could you help me to go in the right direction? Thanks!!! Ricardo

Hello,
I am trying to make my mind about the use of R for Computational and Statistical Approaches to Genomics.

Please, could you help me to go in the right direction?
I am not sure what pointers you are looking for, but checking the CRAN Task Views [1] may be a starting point. Liviu [1] http://cran.r-project.org/web/views/index.html
I'd also suggest you check out http://www.bioconductor.org - "Bioconductor is an open source and open development software project for the analysis and comprehension of genomic data" Richard.

I'm not sure what you are trying to do with R, but maybe you should take a look at the Task Views and see if there is something you can use at your field of work: http://www.stats.bris.ac.uk/R/web/views/ Bart

Thank you so much. All the answers lead me to BioConductor and Task Views. Currently, I've not a precise task to solve, but I do need to draw a landscape about this topic. Your messages have helped a lot. I don't know why, but I don't reach BioConductor website by googling or searchmashing. Cheers, Ricardo.

Dear R-help community, I have searched through the archives and not been able ot find any advice on how to plot a wind field with one arrow per grid square with the arrow pointing in the direction of the wind and it's size proportional to the wind strength. I have the wind speed data in arrays of [lon,lat,uwind] and [lon,lat,vwind] so it is broken down into u and v components. How do I plot it though?!?! Any suggestions very wecome indeed - I seem to have hit a brick wall.....

Hi Jim, I would like to plot something like figure 2 on this webpage: http://www.cnrfc.noaa.gov/storm_summaries/jan1997storms.php My data is very large - covering the whole globe at 2.5deg resolution so longitude=144 girds, latitude=73 grids and time=32 years - hard to give you that data......Would it help to give you a couple of grid squares worth of data for one year? Thanks, Jenny

Hi Jenny, Some time ago, there was a request for a direction field plot. I programmed a basic function, but perhaps the person found another solution, for I never heard any more of it. However, this is not too hard to do in R, even adding the arrows to a geographical plot. Could you post some data and perhaps a link to an example of what output you would like? Jim

Jenny, Have a look at the R Newsletter Volume 3/2, October 2003 Regards, Sean

Hi Jim, I forgot to say that I don't want to create curved arrows, just straight - and I would like them to be proportional to the magnitude :o) Thanks again for your time! Jenny
