I am trying to read a matlab file into R using R.matlab but am encountering this error:

require(R.matlab)
r <- readMat("file.mat", verbose=T)

Trying to read MAT v5 file stream...
Error in readTag(this) : Unknown data type. Not in range [1,19]: 18569
In addition: Warning message:
In readMat5Header(this, firstFourBytes = firstFourBytes) :
  Unknown MAT version tag: 512. Will assume version 5.

How can this issue be solved or is there an alternative way to load matlab files? I can use hdf5load but have heard this can mess with the data. Thanks!
