The package DAPAR is a Bioconductor distributed R package which provides all the necessary functions to analyze quantitative data from label-free proteomics experiments. Contrarily to most other similar R packages, it is endowed with rich and user-friendly graphical interfaces, so that no programming skill is required (see Prostar package).

## </script>The DAPAR and Prostar packages are a series of software dedicated to
the processing of proteomics data. More precisely, they are devoted to the
analysis of quantitative datasets produced by bottom-up discovery proteomics
experiments with a LC-MS/MS pipeline (Liquid Chromatography and Tandem Mass
spectrometry).
DAPAR (Differential Analysis of Protein Abundance with R) is an R
package that contains all the necessary functions to process the data in
command lines. It can be used on its own; or as a complement to the numerous
Bioconductor packages () it is compliant
with; or through the Prostar interface.
Prostar (Proteomics statistical analysis with R) is a
web interface based on Shiny technology () that
provides GUI (Graphical User Interfaces) to all the DAPAR functionalities,
so as to guide any practitioner that is not comfortable with R programming
through the complete quantitative analysis process.
The experiment package DAPARdata contains many datasets that can be used as
examples.
