hdf5.overview {rhdf5} | R Documentation |
This library strives to bring more complete HDF5 support to the R environment in a way that is hopefully natural to the R/S paradigm for working with data objects.
## Not run: # Load the HDF5 library library(rhdf5) # Attach open or create an HDF5 file to the variable "mad." mad <- hdf5.open("microarray.h5") # Create a new group inside the file hdf5.group(mad,"chip1") hdf5.dataset(mad$chip1,"raw", dim=c(534,534)) raw <- mad$chip1$raw for(i in 1:534) { raw[i,1:534] <- runif(534) } # Draw an image of our chip. About 17megs if you try it! image(raw[1:534,1:534]) ## End(Not run)
