Dear All I am having problems to install the package COZIGAM. Despite I have the update version of R (3.0.2) when I try to load the package I cannot find it in the list of available packages. If I try to install it from a local zip file I do get this error message: Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", "Type")) : cannot open the

Dear list, I am using the hurdle model for modelling the habitat of rare fish species. However I do get an error message when I try to model my data: > test_new1<-hurdle(GALUMEL~ depth + sal + slope + vrm + lat:long + offset(log(haul_numb)), dist = "negbin", data = datafit_elasmo) Error in hurdle(GALUMEL ~ depth + sal + slope + vrm + lat:long + offset(log(haul_numb)), :

Dear members, How can I read and plot an ArcGIS raster file into R ? The file has extension .aux and contains floating point bathymetry data. The purpose is to create a spatial model in R that uses ArcGIS map data. I have managed to read and plot various shape files into my R project, but I am stuck with this now. I am new to this list and also to R, so any help would be much appreciated. Many

Can anyone tell me why I would get different average nearest neighbor values for the same set of coordinates between ArcGIS 10 and R? Sometimes the difference in distance is over 1.3 km.

Hi everybody, I heard about "R(D)-COM Stat connector" for ArcGIS, but i am not sure what that is. I did a search in the archive but it seems i am not getting anything back. can anybody explain me what that is, and where i can find more info about it? There is any possibility to run R from inside ArcGIS? there is more than RArcInfo and Shapefile which can

It seems within the last ~3 months Ive been having issues with writing text or csv files from a R data frame.  The problem is multifold and it is hard to filter  out what is going on and where the problem is.  So, Im hoping someone else has come across this and may provide insight.   My current settings for R: R version 2.15.2 (2012-10-26) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1]

Hi everyone, I wonder if anyone knows the reason why the outputs of the same reprojection in r and arcgis are different?. The magnitude of the change can be up to 40 km in the poles. Basically, I have a database of points equally separated by one degree over the globe. In ARCGIS, I am projecting the data in GCS-WGS-1984 and then reprojected it to Berhmann to ensure equal area

Valentina, Si entiendo bien la primer columna de Variables es el nombre de Empresas (un character), no uses esta columna en la función cor, sólo las columnas numéricas. cor(Variables[ , -which( names(Variables) == "Empresas")]) Si no es ese el problema envía str(Variables) para entender mejor la estructura de los datos, y si puedes dput(Variables). Suerte, Daniel Merino El 10 de

con as.numeric tampoco me van los cálculos y no conozco otra manera, pues son alrededor de 40 variables las que tiene la tabla.

Hola, En orden de lo anterior y en tratar de convertir los datos a númericos para poder sacar los estadísticos he hecho lo siguiente generando error: library(xtable) variables <- read.csv("C:/Users/usuario/Documents/Investigacion.csv", header=TRUE, sep=";", comment.char="" , colClasses=c(EMPRESAS="character",

Hola. He estado viendo los datos que adjuntas en el correo. Al ser un fichero Excel xlsx ¿por qué no lo abres directamente? Te aconsejaría la librería openxlsx (si no la has usado nunca , instálala con install.packages(?openxlsx?)) Este es el código que he ejecutado y los resultados que obtengo: library(openxlsx) dat <- read.xlsx("Variables.xlsx") str(dat) Que produce:

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"

I am not sure a previous e-mail reached the list (no mail aknowledgement from R-boundle etc.). The question was how to write polygon or segment coordinates into a shapefile set or any other ArcGIS supported format. The library shapefiles seems to do something but the documentation is a bit beyond of my mind.... and I cannot get the meaning of the functions write**** and its application to the case

Hola Miguel A. Muchas gracias por tu colaboración...pues bien en realidad son nueva con r y no sé aún muchas cosas "básicas". En la primera columna tenía los nombres de las empresas (en letras) y eliminé esa columna, pero me siguen saliendo los mismos errores. Este es un análisis que debo hacer en primera instancia, pero el fin último es realizar un análisis factorial qué aún no se como

Si lo has guardado como csv separado por comas: Abre con cualquier editor el fichero: mira separador de listas y separador de decimal, supongamos que sea "; " para las listas (esto depende de tu configuración regional) y "." para los decimales (es como lo tienes en tu fichero) entonces dat<-read.csv("Variables.csv", header=T, sep=";",

Hi, I am looking for a package to estimate regime switching models (states following a markov chain). I found packages for Hidden Markov Models but I am looking for something a little different: In the HMM the conditional distribution of the observations (give the state) is a known distribution (normal or others), while the package I need should allow to set a conditional distribution (given the
