Reading large .mat file in R

Asked 2022-Mar-20 at 01:38

I am trying to read a large matrix into R. The matrix has dimensionality: 3'987'288 x 93 and is about 3GB large. (Class = double) It is saved as a .mat file (it is not a v7.3 .mat file)

I tried to read the matrix with the R.matlab package:

Apparently V7.3 is not the only incompatible mat file version. As stated in the RDocuments,

readMat: Reads a MAT file structure from a connection or a file Description

Reads a MAT file structure from a connection or a file. Both the MAT version 4 and MAT version 5 file formats are supported.

And long story short, version 4 and version 5 cannot save such large dataset in one file. I think at least 2 solutions are straight forward:

Exchange data in a different file format, e.g. HDF5 or SQlite. Such files are well supported both in R and matlab and do not have the compatibility issue.
Save mat file in matlab in version 4 with the '-v4' switch, but there is an upper size limit in version 4, so you'll likely need to split you data across multiple files.

Cannot modify a matrix element's value with a function

Asked 2022-Mar-02 at 18:33

i'm trying to create a function that sets to 0 the value of every matrix element a[i][j] which is divisible by both i and j. I tried to do it this way but the program just "exits" without giving any error or warning after the matrix=editMat(matrix, nrows, ncols); line.

In R, how to convert a list that contains a list and numeric elements into a data frame

Asked 2021-Jan-05 at 17:44

I have located a .MAT file that contains data that I wish to view in .CSV format, and I do not have a MATLAB license.

Happily, there is an R.matlab package, with a readMat function that enables reading .MAT files into R.

Unhappily, the product of applying readMat to my .MAT file is not a data frame, and I've been struggling all morning trying to figure out how to convert the readMat output into a data frame so that I can export the data as a .CSV file.

Here's the start of my R script:

I have a .mat file containing a matrix of 41 columns and 83 rows of binary values. I have imported it using library('R.matlab') such that ag <- readMat(file.choose(), header = TRUE). I am trying to plot this file like a raster/heatmap, but having no success. I have tried with ggplot2, plot.matrix, and raster.

Set maximum length for generating Delaunay graph in R

Asked 2020-Jul-30 at 02:15

I was trying to generate Delaunay triangulation in R using the spatstat function 'delaunay'. However, I checked the documentation and seems there is no argument to set the maximum length. I noticed this post: How to set maximum length of triangle side in Delaunay triangulation in R? This seems done the same thing as I want, but as my point pattern is large so that I would prefer a simple and quick solution. Thank you!

Here is my code:

ANSWER

Answered 2020-Jul-30 at 02:15

The Delaunay triangulation is a mathematically defined triangulation that does not involve the concept of a maximum segment length. If you want to constrain the maximum length of the segments in the triangulation, then it's not a Delaunay triangulation any more, and the algorithm for computing the Delaunay triangulation is not applicable.

You will have to specify what you want to happen when you impose a limit on the segment length. Should the algorithm just delete the edges which are too long? Delete the triangles that have an edge which is too long? If you delete stuff then the result is no longer a triangulation of the original points. Do you want to produce a different triangulation?

If X is your point pattern, then

Pyinstaller excluding SubModules while Compiling

...

ANSWER

Answered 2020-Feb-18 at 09:22

PyInstaller has a hook mechanism for each package and it handles the binaries needed for the packages.

For some well-known libraries like Qt, it implements an efficient hook file that only retrieves the necessary binaries. But if you want to exclude some parts you need to do it by yourself either by using exclude command or manipulating the hook file:

By excluding the unnecessary modules with --exclude-module. Usually, this would be enough.
By modifying the specific hook file and remove the binaries you don't need.

For example, in Qt's hook file (/utils/hooks/qt.py), there is a variable called _qt_dynamic_dependencies_dict and has all the binaries which located in /Qt/bin so you can remove each one you don't need.

Later in a function called get_qt_binaries which bundles other Qt binaries, you can remove each one you don't need like opengl32sw.dll.
