Win7 (RHDF5) bioconduct installation tips and installed directory not writable problem resolution

In order to read and write HDF5 files in R, the RHDF5 package needs to be installed. The general method is to run in R:

However, this will automatically download the required packages for installation from foreign servers. And my method of improvement is as follows:

1. Access Http://bioconductor.org/biocLite.R with a browser, save the file to a local

2, edit the local BIOCLITE.R, the third row and the eighth line of the comment, the content is changed to:

Options ("Repos" = C (cran= "Http://mirror.bjtu.edu.cn/cran") options ("Bioc_mirror" = "http://mirrors.ustc.edu.cn/bioc/")

This will be even the domestic server download package, the speed will be relatively fast.

3. Running in R

> Source ("BIOCLITE.R") > Bioclite ("Rhdf5")

You can install the RHDF5 package.

Additional installation may encounter error: Installed directory not writable,cannot update packages ...

My workaround is to start the R run environment or Rstudio as an administrator before installing.
