rmatio
is a package for reading and writing Matlab MAT files from
R. rmatio
supports reading MAT version 4, MAT version 5 and MAT
compressed version 5. rmatio
can write version 5 MAT files and
version 5 files with variable compression.
Internally, the rmatio
package uses the C library
matio for reading/writing
MATLAB MAT files.
You can track (and contribute to) development of rmatio
at https://github.com/stewid/rmatio.
To install the latest release on CRAN
install.packages('rmatio')
To install the development version of rmatio, it's easiest to use the
remotes
package:
# install.packages("remotes")
library(remotes)
install_github("stewid/rmatio")
library(rmatio)
Read a compressed version 5 MAT file from an URL
url <- "https://raw.githubusercontent.com/stewid/rmatio/master/inst/extdata/matio_test_cases_compressed_le.mat"
m <- read.mat(url)
View content
str(m)
Write an uncompressed version 5 MAT file
write.mat(m, filename="test-uncompressed.mat", compression=FALSE, version="MAT5")
Write a compressed version 5 MAT file
write.mat(m, filename="test-compressed.mat", compression=TRUE, version="MAT5")
Check that the content of the files are identical
identical(read.mat("test-uncompressed.mat"), read.mat("test-compressed.mat"))
Read a version 4 MAT file with little-endian byte ordering
filename <- system.file('extdata/matio_test_cases_v4_le.mat', package='rmatio')
m <- read.mat(filename)
View content
str(m)
Read a version 4 MAT file with big-endian byte ordering
filename <- system.file('extdata/matio_test_cases_v4_be.mat', package='rmatio')
m <- read.mat(filename)
