midrangeMCP is an “R” package designed to present four new multiple comparison tests. This work was developed during the doctorate in Statistics and Agricultural Experimentation, by the Federal University of Lavras (UFLA/BRAZIL). The supervisor of this work was Professor Daniel Furtado Ferreira. I am currently as Professor of Statistics at the Federal University of São João del-Rei (UFSJ/BRAZIL). Today, we have the collaboration of a student of scientific initiation, Diego Arthur Bispo Justino de Oliveira, student of Mechatronics Engineering at UFSJ.
Four tests are presented, three based on the distribution of the externally studentized midrange and one based on the distribution of the externally studented range, well documented distribution in the literature. There are many distributions based on this last distribution, the difference for our case is that it was used for a test based on grouping methods for multiple comparisons, something similar to what was done with the Scott-Knot test.
The tests based on the distribution of the externally studentized midrange are the Tukey Midrange test (TM test), the SNK Midrange test (SNKM test) and the Means Grouping based on Midrange test (MGM test). Finally, the test based on the distribution of the externally studentized range which is the Means Grouping based on the Range test (MGR test).
Finally, a versatility of the package is the use of the GUI. This feature provides users unfamiliar with the R language when using the midrangeMCP package.
These tests are available in the thesis of the work, and their performance evaluations are presented. The articles of these are in the submission stage, one of which has already been approved by the Journal of Science and Agrotechnology.
To install the midrangeMCP package via CRAN:
install.packages("midrangeMCP")To install via GitHub:
install.packages("devtools")
install_github("bendeivide/midrangeMCP")The package’s functions are: MRbarplot,
MRwrite, guimidrangeMCP and
MRtest. The latter is the main function. From the arguments
inserted in it, the other functions can be performed. In the case of the
guimidrangeMCP function, once executed, it will open the
GUI. From there the database and the necessary arguments for the
functions can be entered.
The package article is still being submitted. But the works mentioned above can assist in citing the package. Still, as the midrangeMCP package is available on CRAN, quote it this way:

Version 3.1 (2020-06-29): Update GUI (guimidrangeMCP
function). Corrections in the graphic device in which the ‘save-as’
button was pressed twice so that the window was opened, when RStudio was
being used. Corrections to the Plot configuration in the ‘save-as’
button. Corretions to the Plot configuration in the ‘Update Plot’
button. Internationalization of ‘Scale of Plot’ to the language in
Portuguese. Internationalization of ‘…Nor will you need to use quotes
between treatment levels…’, part of the message in help button (Average
option -> treatment).
Version 3.0 (2020-06-23): Reactivation of the package to CRAN. There was a change in the design of the graphical user interface using the Tcl/tk language, through the tcltk package. The basic settings of the Interface have been preserved. However, some features of the interface have been changed, such as its color. Another modified feature was the plot area. Some modifications will still be added in the following versions.
Version 2.1 (2020-04-14): Internationalization of the package to the language in Portuguese (Brazil). On 5/21/2020 the midrangeMCP package was removed from the CRAN repository due to a dependency on the gWidgets package. This package has been archived.
Version 2.0 (2020-04-11): Creation of the graphical user
interface using the gWidgets package
with GTk+ language support (gWidgetsRGtk2).
This resulted in the guimidrangeMCP function.
Version 1.3 (2016-07-14): Removing bugs.
Version 1.2 (2016-04-28): Removing bugs.
Version 1.1 (2016-02-21): Removing bugs.
Version 1.0 (2015-11-05): In the first version, we created the
basic functions of the midrangeMCP
package: MRtest, MRwrite and
MRbarplot.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
