A vignette which guides you through all functions of the package is available here.

The package forceR has originally been written for insect bite force data preparation and analysis, but it can be used for any kind of time series measurements. Functions include

• loading, plotting, and cropping of data
• correction of charge amplifier drifts
• correction of baseline drifts
• reduction of sampling frequency
• automatic extraction of single peaks
• rescaling (normalization) of curves
• reduction of curves to 100 time steps each
• finding of best polynomial fits to describe all curves

To install the stable version of forceR from CRAN use the following command:

install.packages('forceR')

You can also install the current development version of forceR from the GitHub repository:

require(devtools)
devtools::install_github("https://github.com/Peter-T-Ruehr/forceR")
