This R package provides functionality for quality control processing, statistical analysis and visualization of mass spectrometry (MS) omics data, in particular proteomic (either at the peptide or the protein level; isobaric labeled or unlabled), lipidomic, and metabolomic data. This includes data transformation, specification of groups that are to be compared against each other, filtering of feature and/or samples, data normalization, data summarization (correlation, PCA), and statistical comparisons of groups of interest (ANOVA and/or independence of missing data tests). Example data to be used with this packages can be found in pmartRdata.
This package makes use of several packages hosted on BioConductor. If
you are encountering warnings about unavailable BioConductor packages
such as pcaMethods
, you may need to add them to
options("repos")
:
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
options("repos" = BiocManager::repositories())
(Recommended) Install from CRAN:
install.packages("pmartR")
# or
::install("pmartR") BiocManager
If you are on Mac/Windows and have a recent R version, you can skip compilation by installing from binaries, see the pmartR CRAN page for available binaries.
install.packages("pmartR", type = "binary")
# or
::install("pmartR", type = "binary") BiocManager
To install the latest release:
::install_github("pmartR/pmartR@*release") devtools
To install a specific release, say v2.4.0:
::install_github("pmartR/pmartR@v2.4.0") devtools
(Not recommended, since these changes are likely still being tested) You can also install the latest changes to master:
::install_github("pmartR/pmartR") devtools
There is a problem that causes pmartR to fail compiling cpp code, which has something to do with rcppArmadillo and certain installations of gfortran. See these posts that try to explain the issue: 1 2 3. The simplest solution if you are on Mac/Windows and have a recent R version is to install from pre-built binaries (see installation section). If you cannot install from binaries, two solutions we have found are:
There are similarly issues with compilation in newer Mac chips. We
recommend to install gcc-13 from homebrew brew install gcc
or the universal version from https://mac.r-project.org/tools/.
Additionally, some users experience errors with
ld: Assertion failed ...
as seen here. One
solution is to use the old linker by making sure gcc uses the flag
-ld64
(Xcode
docs). To do this, you can edit ~/.R/Makevars
to
include this flag, for example by appending it to LDFLAGS with +=:
# in ~/.R/Makevars
LDFLAGS+=-ld64
or specifying it in your compiler command:
# in ~/.R/Makevars
CC=/usr/local/bin/gcc -ld64
To get started, see the package documentation and function reference located here.
Example peptide (both unlabeled and isobaric labeled), protein, metabolite and lipid data are available in the pmartRdata package available on Github, here
See the contributing docs.
