memapp is a web application created to serve as a graphicaluser interface for the R mem package. It was created using Shiny, a webapplication framework for R.
The stable package can be installed from the official R repositories(CRAN) using the built-in install function (or from the packagemanager in some GUIs for R):
# install the memapp CRAN versioninstall.packages("memapp")Or from the official repository:
if(!require("devtools")) install.packages("devtools")library("devtools")# install the memapp stable version from GitHubinstall_github("lozalojo/memapp", ref = "master")To install the development version ofmemapp use thedevtools package.
if(!require("devtools")) install.packages("devtools")library("devtools")# install the memapp development version from GitHubinstall_github("lozalojo/memapp", ref = "development")When installing this version also you are intalling developmentversions of some sensitive packages that are used bymemapp(including themem package).

To run the memapp application, just use the function:
# run the app:memapp::runmemapp()You can specify other parameters passed toshiny::runApp, such asdisplay = normal,orlaunch.browser = TRUE.
# run the app:memapp::runmemapp(launch.browser = TRUE)In order to use the Surveillance/Animation graph,magickpackage must be installed:
install.packages("magick")Along withImageMagick:
To import other formats like SAS, Stata, SPSS, excel, you’ll needadditional packages:
# MS Excel(xls, xlsx)install.packages("readxl")# dBase (dbf), SPSS (sav) and Stata (dta)install.packages("foreign")# SAS (sas7bdat)install.packages("haven")# OpenDocument Spreadsheet (ods)install.packages("readODS")# MS Access under Windows (mdb, accdb)install.packages("RODBC")The installers can be downloaded from their webpages or can beinstalled directly from R:
# check if installr is installed, and install it otherwiseif(!require("installr")) install.packages('installr')library("installr")# install ImageMagickinstall.ImageMagick()Most data can be exported to csv or excel files, but for the later towork you have to install Rtools toolset and the openxlsx package.
You can download and install Rtools it here:
# check if installr is installed, and install it otherwiseif(!require("installr")) install.packages('installr')library("installr")# install Rtoolsinstall.Rtools()And install openxlsx package:
# Install openxlsx packageinstall.packages("openxlsx")The technical manual of the application can be downloaded fromhere:
