Tidying methods for Biobase's ExpressionSet objects
## S3 method for class 'MSnSet' tidy(x, addPheno = FALSE, ...)
x |
MSnSet object |
addPheno |
whether columns should be included in the tidied output for those in the MSnSet's phenoData |
... |
extra arguments (not used) |
addPheno=TRUE adds columns that are redundant (since they
add per-sample information to a per-sample-per-gene data frame), but that
are useful for some kinds of graphs and analyses.
tidy returns a data frame with one row per gene-sample
combination, with columns
protein |
protein name |
sample |
sample name (from column names) |
value |
protein quantitation data |
if (require("MSnbase")) {
library(MSnbase)
# import MSnSet object
data(msnset)
# Use tidy to extract genes, sample ids and measured value
tidy(msnset)
# add phenoType data
tidy(msnset, addPheno=TRUE)
}
