Hi all, I wish to implement various landscape ecology measures through R, such as: box counting dimension; twist number statistics; contagion and lacuniarity indices; angular second moment; adjacency measures; dominance indices; etc ... Some of the measures can be applied to shape analysis and classification. Is anyone implementing any of these measures? If so I would like to contribute and

Manuel: I changed your variable names from x to 'long' and y to 'lat' on the riqueza_out.csv file. The code below should do what you want. Also, since the legend title is kind of long, I broke it down into three lines so you can see more plot area. I am cc'ing the other groups so more people use it if needed. library(rgdal) library(ggplot2) library(sp) library(maptools)

Dear Zongshan Li, I'm forwarding this back to r-help ... it's generally best to keep the conversation going in public, so that (a) other people can chime in with ideas and suggestions, (b) your question doesn't get lost if the original respondent doesn't have time to deal with it, (c) the answers are archived for future reference. Your example (I've attached it, hope it

I am having problem printing in Landscape mode. I have a program that requires landscape printing. I have a Canon ip2770 attached directly to my machine, and is configured properly in Cups, correct driver and all. OpenOffice works perfectly in Portrait and Landscape printing. In Wine, Portrait printing works perfectly for my program and the Wine Notepad. However, in both my program and the

Dear Barry, Thanks for your stimulating reply. As you see I have send a CC of this reply to the R mailing list. The R mailing list will be the best place to send your queries. You can subscribe here: http://www.r-project.org/mail.html I would think there is an interest in the provision of landscape indices analysis methods in R. There are several packages for landscape indices analysis

Is there a set of R expressions that has the same effect as the following set of S-Plus 2000 expressions: graphsheet(format="printer", orientation="landscape") par(mfrow=c(2,2)) plot(x1, y1) plot(x2, y2) plot(x3, y3) plot(x4, y4) dev.off() # one page of landscape plots sent to printer I am having trouble with formulating the equivalent of the first line of the above in R.

Hi: I am haviong problems with Landscape mode on our HP printers (many models). I am running 2.2.7a on two different servers. One is using the "old style" printing (using "printer driver file" parameter). The other is using the newer printing system. It is the same code on both. Both are Solaris systems. For the old one, the drivers are installed on the client, for the

Hello together! How can I plot a landscape letter-format plot? With postscript, I just use the horizontal option and I get what I want, but it seems that the pdf lacks this option. Well, I could do a ps2pdf conversion of the generated ps-file. But is there a way to directly produce landscape pdf-plots with R? Thanks for any help. Greetings, Sebastian

Dear all: Does anyone have any suggestions on how to make a spatially explicit landscape with spatial autocorrelation in R? In other words, a landscape where all cells have a spatial reference, and the environment values that are closer in space are more similar (positive spatial autocorrelation). Thank you, Laura

Dear all: I would like to create a landscape of environmental values that follow a uniform frequency distribution and also have spatial autocorrelation in the landscape. I was wondering if there is an algorithm and/or package out there that creates autocorrelation of values that are distributed according to a non-normal frequency distribution. Any suggestions are greatly appreciated. Thank you,

I'm trying to figure out how one might go about simulating a landscape (matrix) in R. For example if one wanted to generate a simulated landscape of precipitation values for some area (say a 100 X 100 matrix) they could generate 10,000 numbers using a random normal distribution with a mean and std. dev. and randomly allocate these generated numbers to the grid cells. However, this is too

Our environment: Samba 2.2.5 on RedHat 7.2 (Tried on two different servers) Printing handled by Cups 1.1.14-15 Printers shares available and print jobs being handled properly by cups. THE PROBLEM: New HP drivers uploaded to the PRINT$ share seem to be downloaded by clients correctly, however the following problems occur: 1.

Hi, I made a few graphs by ggplot. The following codes produce a pdf file with graphs in landscape orientation on my Windows PC, while they produce a pdf file with the same graphs, but in portrait orientation: *p2 <- lapply(1:(2*n), function(.x) xyz_outl[.x][[1]]) #a sequence of graphs made by ggplot* *m2 <- marrangeGrob(p2, nrow=3, ncol=2) * *ggsave("xyz.pdf", m2)*

The MabLab at the University of Florida's Fort Lauderdale Research and Education Center (Davie, FL) is looking to fill an immediate opening for the position of a Biological Scientist. We are looking for an enthusiastic, highly motivated and responsible individual to join an exciting research team focused on spatial ecology, from fine-scale movement and habitat selection to range dynamics.

Does anybody know how to get a pdf file with landscape orientation?. pdf(file= 'my_file.pdf' ,onefile=T,paper='A4') plot(sin, -pi, 2*pi) dev.off() Thank's in advance Juan A. Hernandez Spain [[alternative HTML version deleted]]

Hello listers, I would like to know how I can get the resulting graphic of the function plot.hclust (from the package cluster) in landscape orientation. Is it possible? Thanks, Juan

Hello All, I 'm trying to plot R graph in landscape orientation in a .rtf file. i 'm using library(rtf) for this. do we have any option in addPlot() function to rotate the orientation of the rtf file?

has there been an update on the dll for printing, am still having landscape printing problems. It seems to get cut off for longer than letter size papers. It prints but it stops when it reaches the end of a letter sized page. Even if i output a pdf and print that it gets cut off the same way. Please help. BTW, I can't attach a sample PDF file, but here is a sample file I uploaded to my

Hi, How can I use portrait/landscape option in lattice bwplot? Is there any option in trellis.device where I can define this? Thanks in advance, Mahbub.

I use the following function to export some figures to .eps: p.eps <- function(p, fname, title = NULL, width, height) { postscript(file=fname, onefile=FALSE, paper="special", width=width, height=height, horizontal=FALSE) print(p + opts(title = title)) dev.off() } Whenever I have a page consisting of *only* figures exported in this way, Acrobat Reader shows them in
