With WinXP host, RH8 VMware guest, at level 3, I issue: mount -t smbfs -o user,noauto,dmask=777,fmask=777,username=xx, password=yy //DELLBOX/linuxShare /mnt/linuxShare and get: Connection to DELLBOX failed SMB connection failed timeout connecting to 192.168.113.1:139 Error connecting to 192.168.113.1 I cannot find this IP address anywhere.

Dear all, I've been using R on a Mac to process some data for export to ArcMap GIS (which only runs on Windows). ArcMap seems to require tab-delimited data (my data are in 3 columns), so I've been using the sep="\t" argument. However, this resulted in strange end-of-line characters when displayed on a PC. I looked in the write.table help file to find that eol="\r\n"

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

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.

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?

I have a large matrix full of probabilities; I would like to convert each probability to a 1 or a 0 using rbinom. How can I do this on the entire matrix? The matrix was converted from a raster ArcMap dataset, so the matrix is essentially a map. Because of this, I have no column headings. Thanks! -- View this message in context: http://www.nabble.com/rbinom-for-a-matrix-tp18366867p18366867.html

Dear users, I am trying to export polygons from Arcmap into Spatstat to run some simulations using functions available in Spatstat package. One particular area to be exported is formed by a number of polygons defining the external boundaries of the area (as a groups of islands) and a number of polygons inside the previous ones, as ?holes? not to be considered as part of the area. I have

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

I recently reinstalled RH8 as a VMware guest on a WinXP box. I used a previously proven script at level 3, containing, in one line with no inappropriate spaces: mount -t smbfs -o user,noauto,dmask=777,fmask=777,username=xx, password=yy //DELLBOX/linuxShare /mnt/linuxShare I get a failure that reports numerous possibilities including bad fs, and other other things. I suspect I omitted a

Hello, I have five raster files in ASCII format. With four of them I have no problem extracting values based on a set of X and Y coordinates. Unfortunately with one of the files all I managed to extract is NA values. To verify the problem I have opened the raster with ArcMap and there are no NA values where I am extracting. I have also plotted the spatial point class on top of the raster in

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

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

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="-")

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

List, I am trying to extract summary statistics from a data frame with several variables (and NAs) into a dataframe with the columns: Variablename (ie the colnames of original data), mean, stdev, max, min, Valid N, Missing Values. Extracting the statistics is straightforward using stack and aggregate. However, I haven''t succeeded in obtaining the number of Missing Values. I can extract

Hi List, I am trying unsucessfully to modify the fontsize of lables in mosaic: require(vcd) mosaic(Titanic, pop=FALSE, labeling_args=list(rot_labels=c(bottom=90,top=90), set_varnames = c(Sex = "Gender"), gp_text=gpar(fontsize=20))) #can't get it to resize text tab <- ifelse(Titanic < 6, NA, Titanic) # it works for labeling_cells labeling_cells(text = tab,

Hi everyone, A beguinner question. - How shall i import 9 different ascii (created from a gis layer (arcmap grid)) into R to create a single dataframe for using in hier.part? Should i use read.table, then turn each created object into a single vector using unlist and finally use data.frame to joint all the vectors into a unique data frame (xcan in the usage of hier.part) ? I´ve been trying to
