DWDataReader

R package to import data from DEWESoft data files (dxd, dxz extensions).

Description

This package is based on the DEWESoft Data Reader Library. With this package you can import reduced (Min, Max, Average, RMS) and fast data from analog or digital channels.

Note : this version can only import simple analog / digital data (no matrix like available with FFT).

Installation

Prerequesites

• R (>= 4.3.1)
• Rcpp must be downloaded and installed.
• devtools must be downloaded and installed.
• DEWESoft Data Reader Library (>= 4.2.0.24) must be downloaded and DLLs should be copied in the working directory.

Procedure

The easiest way to install it is to use RStudio along with devtools and Rcpp.

install.packages(devtools)

install.packages(Rcpp)

Open the project in RStudio, then, click on Build » Install package.

Once it is built & installed, the following line shouldn't give any error :

library(DWDataReader)

Usage

To use the library, just create a new object as usual :

lib <- new(DWDataReader)

Then open the file you want to access (an example file is available in the test directory) :

# Please take care of the extra '\' in the filepath

lib$openFile("C:\\test.dxd")

/!\ Be aware that you may need to copy the DEWESoft Data Reader Library DLLs in the working directory to make it work.

You can now get access to the data inside the file.

lib$getChannels()

lib$getChannelReducedData("channelName",3)

lib$getChannelData("channelName")

Debug

You can have a better understanding of how the library works by defining the SHOW_DEBUG_INF FLAG in DWDataReader.hpp in case of a crash or freeze.
