Re: [R] Problem with my function using as.POSIXct

You have succeeded, but you just don't know it. The POSIXct object is representing that instant of time internally... you are just complaining about how it is printing it. So convert it to character explicitly with the desired format when you want to print it. as.character(

[R] Problem with my function using as.POSIXct

Hello all: I wrote a function: my.bastimeToSynoptic <- function(x) { f<-unlist(strsplit(as.character(x), " ")) hr<-unlist(strsplit(f[2], ":")) if(as.numeric(hr[1])<6) { synoptic<-"00" } else { synoptic<-as.integer(as.numeric(hr[1])/6)*6 }

Re: [R] can not install package "matie"

Varin In the teaching you to fish department, you can find those dependencies Duncan appeared to pull out of thin air by looking at the CRAN contributed packages web pages, which can easily be found with Google. Start at the matie page and follow the dependency links and look at dependencies.

Re: [R] Creating the right table from lapply list

Perhaps this toy example will help: ## example data output <- list(1:5, 1:7, 1:4) lens <- lapply(output, length) maxlen <- max(unlist(lens)) outputmod <- lapply(output, function(x, maxl) c(x, rep(NA, maxl-length(x))), maxl=maxlen) outputmat <- do.call(cbind, outputmod) write.csv(outputmat,

Re: [R] Creating the right table from lapply list

If I understand correctly, this query is really about how to organize your data, not how to use R code to do it, though that may come later. Of course, the first question is why mess with Excel at all? But I shall assume you have good reason to get your data into Excel and do what you want to with

Re: [R] Using R and the Tidyverse for an economic model

Jeff, thanks for taking the time to read and comment. About the points you raise: 1) Packages. I do understand the advantages of packages. But I'm still prototyping, and it seemed too complicated to make every source file a separate package, when I'm still often moving source code from one to

[R] coxme in R underestimates variance of random effect, when random effect is on observation level

Hello, I have a question concerning fitting a cox model with a random intercept, also known as a frailty model. I am using both the coxme package, and the frailty statement in coxph. Often 'shared' frailty models are implemented in practice, to group people who are from a cluster to account

Hi Ben, Adding 'band' to raster provided what I want; importnetcdf <- raster(file.nc,band=4) writeRaster(importnetcdf,file.tiff,"GTiff",overwrite=FALSE) Thanks for your help. Ahmed Ahmed Attia, Ph.D. Agronomist & Soil Scientist On Wed, Mar 28, 2018 at 11:53 AM, Ben Tupper

Re: [R] netCDF to GeoTIFF by layer in r

Hi Ahmed, When reading from a ncdf file you can use the 'varname', 'lvar' and 'level' arguments - see the 'Details' section in the docs https://www.rdocumentation.org/packages/raster/versions/2.6-7/topics/raster We

[R] Fwd: netCDF to GeoTIFF by layer in r

Hi Ista! Thanks a lot for your support!! It puzzles me because it’s the first time that something like this happens to me. I’m aware that root and user don’t have the same environmental variables here. However, I don’t know why root chooses Java 9 and my user chooses Java 10. Isn’t Java 10

Hi Jeff!! I really don’t know if running R CMD javareconf with sudo has posed a problem here, now or in the past. What I know is sometimes it’s the only way to really config it, if I don’t run with sudo, in the end it asks me if I want to overwrite the configuration from root override
