Dear Users, I report an issue that I encontered on R using rhdf5 h4ls function. Here is the example :
 
library(rhdf5)
file_loc <- file.path(tempdir(), "h5ex_d_sofloat.h5")
download.file(url = "https://support.hdfgroup.org/ftp/HDF5/examples/files/exbyapi/h5ex_d_sofloat.h5",
              destfile = file_loc,mode="wb")
h5ls(file_loc)

Linux output :
  group name       otype dclass   dim
0     /  DS1 H5I_DATASET  FLOAT  x 32

Windows ouptut :
  group name       otype dclass     dim
0     /  DS1 H5I_DATASET  FLOAT 64 x 32

As you can see, the dim columns has been truncated.​

Here are the session info :

Thanks in advance

Sorry for the delay in replying to this.  For future reference, on this board it's normally good practice to give the name of the package you're having issue with as one of the tags.  I get notified if there's a post tagged rhdf5 but I don't look out for the individual functions.

I'm don't have a specific reason why the formatting is wrong in the Linux version, but you're using different versions of R and rhdf5 in your comparison.  I suspect there was a change made between the 2.14.0 and 2.20.0 that fixed this problem, and if you use a more recent version on Linux the issue will go away.  Here's my output and sessionInfo running your example and using the current release on Linux Mint:

0     /  DS1 H5I_DATASET  FLOAT 64 x 32
