Hi Arnaud, Something like: r <- raster() projection(r) projection(r) <- "+proj=lcc +lat_1=48 +lat_2=33 +lon_0=-100 +ellps=WGS84" projection() Might help, Best, Jan On 15/11/13 17:52, "Arnaud Mosnier" <a.mosnier at gmail...
Hi, I trying to export data from large images (satellite data) in to MySQL data via R. The code works fine but after some time it gives to following error: " *** caught bus error *** address 0x100000012, cause 'non-existent physical address...
Dear Sofea, You could try something like this: fun3 <- function(x){ time <- 1:length(x) xc <-cos(2*pi*t/365) xs <-sin(2*pi*t/365) fit <- lm(x~xc+xs) return(fit$coefficients[1]) } s3 <- calc(s, fun...
Hi, I trying to export data from large images (satellite data) in to MySQL data via R using RMySQL (RMySQL_0.7-5.tgz installed via R Console). The code works fine but after some time it gives to following...
Hi Jordan, Nice reproducible example. The following should work: rc <- mask(rc,r) # instead of mask[rc,r] Only if your raster's are very large you'll have to watch out overusing the RAM: If possible in that case...
Dear all, I have just upgraded from 2.13.2 to 2.14.0 on my mac book pro on 10.6.8 OsX. After installing the "zoo" package - I am unable to load the zoo package in R using...
I did a quick test here and it runs fine here (via the terminal/Rstudio). One thing that might help is to do: update.packages(checkBuilt=TRUE) Hope this helps, Jan > library(raster) Loading required package: sp > library(rgdal) rgdal...
Simon, I have downloaded the R.app GUI (R-GUI-5944-2.14-leopard-Leopard64.dmg) from http://r.research.att.com/. Everything works fine, when launching the R.app and loading the "zoo" package. I have deleted the R64...
You could use the calc() environment and define your own function where you create a ts() object and then subset the ts() using window() to your time period. f_subset <- function(x) { x <- ts(x, start = c(1901, 1), frequency...
Dear Guillaume, 1) seasonal is a ?helper? function for the plot.bfast() function in case ANOVA = TRUE https://github.com/cran/bfast/blob/master/R/plot.bfast.R https://github.com/cran/bfast/blob/master/R/seasonal.R 2) regarding...
Check out GRASS functionality https://grasswiki.osgeo.org/wiki/LIDAR which can be very efficient as nicely combined with R via https://grasswiki.osgeo.org/wiki/R_statistics Cheers, Jan --- www.wageningenur.nl/changemonitor On 31/08/15 10:43...
As the error message says the error comes from testing your function on a subset of your raster stack/brick i.e. x[1:5]. See below for a small example: require(raster) # create data r <- raster(nrow=10, ncol...
