tmod (version 0.50.13)

makeTmodFromDataFrame: Convert a data frame to a tmod object

Description

Convert a data frame to a tmod object

Usage

makeTmodFromDataFrame(
  df,
  feature_col = 1,
  module_col = 2,
  title_col = NULL,
  extra_module_cols = NULL,
  extra_gene_cols = NULL
)

Value

A tmod object

Arguments

df

A data frame

feature_col

Which column contains the feature (gene) IDs

module_col

Which column contains the module (gene set) IDs

title_col

Description of the modules (if NULL, the description will be taken from the module_col)

extra_module_cols

Additional columns to include in the module data frame

extra_gene_cols

Additional gene columns to include in the genes data frame

Details

`makeTmodFromFeatureDataFrame` converts mapping information from features (genes) to modules (gene sets). The data frame has a row for each feature-module pair.

`makeTmodFromModuleDataFrame` converts mapping information from features (genes) to modules (gene sets). The data frame has a row for each module, and all gene IDs corresponding to a module are stored as a comma separated string, e.g.

Vice versa, `tmod2DataFrame` converts a tmod object to a data frame.

Examples

df <- data.frame(
gene_id=LETTERS[1:10],
geneset_id=rep(letters[1:2], each=5),
geneset_description=rep(paste0("Gene set ", letters[1:2]), each=5))
res <- makeTmodFromDataFrame(df, 
  feature_col="gene_id", 
  module_col="geneset_id",
  title_col="geneset_description")
