Hi ! I need a plot for data extending over several orders of magnitude on the y axis. The following command generates a nice looking semi-log plot for my data: plot(x,y,log="y",type="l",lty=3, ylim=c(0.01,2),yaxp=c(0.01,1,1),las=1) I would appreciate having also minor tick marks in-between the 3 major ticks obtained with the above command. The "minor.tick" function

Hellow everyone, This code bellow will calculate average daily wind speed(measurements are taken every three hours).Any ideas how to take the Min and Max instead of average. library(Matrix) setwd("C:\\Users\\aalyaari\\Desktop\\img") listfile<-dir() long <- file("C:\\Users\\aalyaari\\Desktop\\New folder (5)\\inra.bin", "rb") A=readBin(long, integer(),

Dear all, I would like to import a range of cells (e.g. F10:K234) from an Excel worksheet to R. I have looked for documentation on RODBC and RDCOMClient but I was not able to find enough information to solve my problem and all the examples I have seen were dealing with an entire worksheet, not a range of cells. Thanks, Jean-Noel Jean-Noel Candau INRA - Unit? de Recherches Foresti?res

I'm having a problem here I'm not sure how to solve, so I hope someone else have done the same (and succeeded :) I have an old smb server ('tux') which is ancient (both in software and hardware) and can't handle the load. This machine is running version 2.2.3a-14.1 (Debian GNU/Linux woody) with 'character set = ISO8859-1'. The new smb server ('bella') runs

I want to write to M, using row and columns taken from A and B, with values from C. C is a lot longer than A and B, so only the first 67420 elements of C are used in my loop.So how can I improve it to take then the next 67420 and write it to new file and so on till the 248th 67420. Many thanks library(Matrix) M <- Matrix(-9999, 360, 720) ## creat matrix with 720 columns and 360 ro ws

Dear all, I would like to perform a regression tree analysis on a dataset with multicollinear variables (as climate variables often are). The questions that I am asking are: 1- Is there any particular statistical problem in using multicollinear variables in a regression tree? 2- Multicollinear variables should appear as alternate splits. Would it be more accurate to present these alternate

This code will read binary file and display it as a map. may problem is that this code is using a continuous colour scheme, even though I have discrete data (which is a classification scheme). How can I map numbers to colours with raster? Please require(raster) conne <- file("C:\\lai.bin", "rb") sd<- readBin(conne, integer(), size=1, n=360*720, signed=F)

I have two binary files(rasters) with the same dimensions. The first file is called `over` and the second is `corr`. I want to replace values in `over` by `NA` whenever `corr` is greater than 0.5. to read the two files we can use: conne <- file("C:corr.bin","rb") over <- readBin(conne, numeric(), size=4, n=1440*720, signed=TRUE) frf <-

Hello, I have setup a centos server running 5.5 and I have a problem with the FTP settings. Currently I have two FTP accounts based on that server, they lead to: /home/bella /home/carmen Currently the FPT accounts starts in the home directory when they are logged in. But they are able to see all directories on the server. What can I do to make sure they cant come out of there home directory?

Dear All, The code given bellow is to extract values of one region and write that to a text file(there are 365 binary files in the directory). The problem which I am facing is that all my files are binary with size of 360 rows and 720 columns. I specified that in this line: file2<-matrix(data=file,ncol=720,nrow=360) but I got an error : Error in mean(file2[X, Y], na.rm = TRUE) : subscript

All, This is a fresh, un-f#$ked-with OpenSUSE install after adding the Tumbleweed repository and doing a dup. I installed the Hypervisor with Tools for which it prompted me for Xen or QEMU and I chose Xen. No bridge was made. When I go to create a fully virtualised machine, it nao has the error: Error: Device 0 (vif) could not be connected. Could not find the bridge, and none was specified.

Suppose we have files in one folder file1.bin, file2.bin, ... , and 1460slice(file) with dim of 720 * 360 in directory C:\\PHD\\Climate Data\\Wind\\ and we want to read them and make a loop to go from 1 to 4 and take the average, then from 4 to 8 and so on till 1460. in the end we will get 365 files . I need those 365 files to be in one new folder for later use in my model I tried using this

I have 365 binary files: https://echange-fichiers.inra.fr/get?k=oy3CN1yV1Um7ouRWm2U ,I want to calculate the monthly average. So from the 365 files, I will get 12 files.I would like also to tell R not to take into account the no-data value (-32765).for example, for the first month, there are 31 records: 3 of these records has the value -32765,I want R to take the average of the rest records(28

R-devel: I am encountering a consistency issue using socketConnection and readBin with *non-blocking* connections on Unix and Windows XP (no Vista to test). I am a bit confused by the behavior of *non-blocking* connections under Windows specifically. When calling readBin on a non-blocking connection when there is no data to read on the socket, the connection under Unix will return a vector of

Good Morning i am in doctorate. i want to ask for the packages of R, i tried to install it, but it appears " not found". each time i have to delete and install again the programme R. Are there another method for installing the package? thank you

Hi all, I obtained negative values for AIC and BIC criteria for a particular model that I have developped... I don't remember to have negative values for these crietria for others applications, so I am a little suprised... Could anyone tell me if something is wrong or his conclusion concerning my model? Best regards, Olivier.

Hello I created a radar chart using the function of ?radarchart? from the ?fmsb? package in R software. The matrix I am using is as follows: x<-c(c(rep(4.5,7),c(rep(0,7)), 3.34, 3.28, 1.37, 1.12, 3.52, 4.07, 3.66)); a<-matrix(x,nrow=3, ncol=7,byrow=T) I would like to show the range of c(0,5) on the axis instead of c(0,100) or c(0,1). I really appreciate it if any body can guide me.

Hello! I have problems with using of "readBin" to read files, which was written in C with "fwrite". In the C-File there is the following Code: fwrite(MyitINI,sizeof(itINItype),1,outfile); where MyitINI is a structure of the following form typedef struct{ int KernelFileSave; /* Determined, if Systemmatrix saved or not.*/ char KernelFileName[200]; /* A-Matrix name

Hi, I would like to interface a C code into R. Is it possible to use in the C code, functions from a R package (for instance, to use pmvnorm within loops in the C code and to call the result in a R function)? Nathalie

I often use Lyx/Sweave and I typically write in english. Today I had to write a document in Italian and, as many of you know, many italian popular words use ?, ?, ?. ?, etc. I discovered that if I type in Italian (that is there is at least one letter with accent) with the Sweave module selected lye is not able to correctly compile the document. I tried to change the input encoding, but it
