[R-sig-Geo] plot() and Jpeg() increase font size and resolution
Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs. Any help would be appreciated Thanx Herry R2.4 on Mandriva 10.2 linux.

blotched y-axis text in plot function
Hi List, I have recently upgraded to opensuse10.2 and R 2.5 (compiled from source). Now, whenever I use plot the y-axis and labels are black blotches while x-axis and labels are fine. Using demo(graphics) this occurs with plot/boxplot/hist/pairs/coplot but not in the pie graphs and in the "The level of Interest in R" plot, which uses axis to define the y-axis. I presume this has to

error: GLX extension missing on server
Hi List, when loading library(rgl) I get error "RGL: GLX extension missing on server". I have Mesa and xgl installed, but xgl info sais its an highly experimental code. Does this mean I shouldn't bother for a while with opengl or are there alternatives?

plot() and Jpeg() increase font size and resolution
Dear list, I am having troubles increasing the fontize when plotting a variogram{gstat} and its model (vgm) with plot and using jpeg(). Also the resolution in the jpeg call does not work. I am using R2.4 on Mandriva 10.2 linux. I can change fontsize with cex.axis in a normal plot, so I presume it has to do with plotting the variogram model. Any help on how to increase the font size and

surface3d grid from xyz dataframe
Hi List, I am trying to plot a grid with an overlayed height. I have a dataframe with four variables: x,y,gridvalue,height. The dataframe has 2.5mio observations (ie grid points), I assign colors through the gridvalue using map_color_gradient thus producing: x,y,gridvalue,height,gridcol as variables of the dataframe. The grid dimensions are 1253 x 2001 (=2507253 data points). My attempts with

summarizing dataframe
Hi Listers, Surely, I just have a mental block and there is a more elegant way of creating a summary count (other than extracing it from ftable). I''d like to create a new data.frame containing counts of spell by loc ie have three columns showing spell,loc,count. Below the data.frame... Any help appreciated Thanks Herry spell loc 101 Parts 1 102 Overall 2 105 Parts 1 106

?replace characters within vector data
Hi List, I want replace characters within a vector. Outside R I could use sed, but I'd like to automate it in R. For example vectorx xxxyyz xxxyyza xxxyyzzb I want to change to: vectorx aaayyz aaayyza aaayyzzb The obvious replace command only deals with whole data entries? Any hints would be appreciated. Thanks Herry

raster time series statistics
Hi Herry, This is probably due to a call to strptime (or similar). No, it doesn't accept %Y-%m as a valid format. Maybe add a constant day to all the dates as that will work: dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12))) timelst<-paste(unlist(dt['year']),unlist(dt['month']),"01",sep="-")

R-crash using read.shape (maptools)
Hi List, I am trying to read a large shapefile (~37,000 polys) using read.shape [winxp, 1gig ram, dellbox). I receive the following error: AppName: rgui.exe AppVer: 1.90.30412.0 ModName: maptools.dll ModVer: 1.90.30412.0 Offset: 0000309d The getinfo.shape returns info, and the shapefile is readable in arcmap. Any ideas on how to overcome this? Thanks Herry

for loop doesn't stop with upper loop value

special characters in linux using dev.print
