I wish to do a stacked area chart to show how relative proportions of species within a stand have changed over time. I know this is simple, but can someone point me to the right function (if it exists). I have not had any luck finding it in the R-help, but maybe I am searching using the wrong keywords.

Is there a package, or does anyone have code they are willing to share, that would allow me to simulate sampling of dead wood pieces across an area? I am specifically looking for code to simulate the dead wood distribution as small line segments across an extent, and then I will "sample" the dead wood using different sampling techniques including line transects, fixed area plots, etc.

Just a quick question. Is there a way to easily specify factor levels in a function definition within nls? For example, I am trying to fit a 3 parameter, nonlinear Weibull function to tree height and I would like to have results by species (or down the road a bit, by plot). I am hoping there is someway to do it easily, similar to the "gas example" in the ANCOVA chapter in Modern

Could someone give me a hand with the format of the gsummary function? Basically, I have a large set of xyz coordinates generated by LiDAR data (>37 million points) and I am trying to derive various summary statistics on the z-coordinates by a grid cell. I wrote a function to do this by creating factors from the x- and y- coordinates and then using gsummary. However, I want the function to

Does someone out there have an example of R-code for a split-split plot ANOVA using aov or another function? The design is not balanced. I never set up one in R before and it would be nice to see an example before I tackle a very complex design I have to model.

R community: I have been creating code for plotting nomographs, or multiple, overlain contour plots of z-variables on a common x- and y- variable. My input has been a matrix with observed x, y, and multiple z variables; I then create a trend surface using trmat for each z-variable. So far so good. One application I have for these, requires shading a portion of the nomogram that meets criteria

I am modeling a trend surface using trmat and want to trim the resulting matrix to the area enclosed by my real data (i.e., remove all the extrapolated areas). I was using chull and in.chull to calculate the convex hull and change all the other values created by trmat to NA. However, my real data has portions that are slightly concave so chull would give me slivers that are extrapolations from

Dear R-help, I have a loop, which is set to take about 26 hours to run at the rate it's going - this is ridiculous and I really need your help to find a more efficient way of loading up my array gpcc.array: #My data is stored in a table format with all the data in one long column #running though every longitute, for every latitude, for every year. The #original data is sotred as

I have been trying various ways and looking though the lists, but I can't seem to find a solution. I am running a Ultra2 with Solaris 9 and rsync 2.5.2, with the old -move-files patch. I want to upgrade to 2.6.3 with the delete-sent-files patch. Which I understand is the new and improved version serving the same purpose. Unfortunately my patch under Solaris did'nt work, so I d/l

Interesting read in Alec Saunders blog today. http://saunderslog.com/2007/03/01/mashable-telcos/ Thought it may interest some people on this list. As food for thought, why it is that ITSP's haven't come up with more 'interesting' voice applications? When asterisk first became available I thought it was the beginning of seeing really neat applications, think Verzion's

Hello all. I was recently the victim of a SIP flood attack. I'm wondering what is the best method to prevent such things in the future.

How do you hide all the green passing examples from the output? I don''t need to know what has passed and it means I have to scroll to see what has failed. -- Posted via http://www.ruby-forum.com/.

Wondering if someone could tell me what would be involved to add support for jumps (within asm block, between asm blocks, and between C/C++ and asm blocks) for Microsoft inline assembly? Is there a rough feel for where it is on the roadmap? Thanks, -Allen -------------- next part -------------- An HTML attachment was scrubbed... URL:

I been revising my list of options for people to connect to my icecast servers. And would like to know what clients you use to connect. I know of the list on the site and I would like to know what you guys use. Please Post Name, Version, OS and Why you choose or recommend this client. I use SAM by Spacial Audio, its a old version, for windows, Why because I got a good deal on the cost of it, it

I know this is a long shot, but does anyone out there have code for converting a R-dataframe into a Stand Visualization System (SVS) tree list? It would save me a bit of time. I would be interested if anyone has FVS code as well. I will be working (reworking) NE-TWIGS equations to a regionwide dataset. Thanks in advance, Mike Mike R.

Hi there, I'm currently running IMAP with Courier and POP3 with Solid-POP3d. I'd like to migrate IMAP and POP3 to both use Dovecot. All this works fine in testing, except for the fact that I have two types of users for legacy reasons. One type of user has a Maildir-style inbox at ~/Maildir/ The other type has a mbox-style inbox at ~/Mailbox Is it possible to make Dovecot look for

The October 2006 R News had an article in which the authors discussed a new package that implemented the Birnbaum-Saunders distribution. However, the package (aptly named "bs") does not appear to be available for installation. Does anyone know the status of this package? Thanks. Tom La Bone [[alternative HTML version deleted]]

Hey, The IPs from SL are from the DJ boards and the like that retrieve the stream information. They don't listen to the stream just pull the stram info. We support shoutcast connections, the firewall passes the port number + the next highest one. Therefor we open port 9000 for listeners, and 9001 for stream sources. This seams to work well for the shoutcast mount. This is all
