Converts a list object or several data.frames of FT-MS data to an object of the class 'moduleData'. Objects of the class 'moduleData' are lists with two obligatory components e_data and f_data and one optional component, e_meta.
as.moduleData(
e_data,
f_data,
e_meta = NULL,
edata_cname,
fdata_cname,
module_cname,
module_node_cname,
instrument_type = "12T",
db = NA,
...
)a \(p \times n + 1\) data.frame of expression data, where \(p\) is the number of observed module nodes and \(n\) is the number of samples. Each row corresponds to data for each peak. One column specifying a unique identifier for each peak/mass (row) must be present.
a data.frame with \(n\) rows. Each row corresponds to a sample with one column giving the unique sample identifiers found in e_data column names and other columns providing qualitative and/or quantitative traits of each sample.
a data.frame with \(p\) rows. Each row corresponds to a module node with one column giving a unique module node identifier (must be named the same as the column in e_data) and other columns giving meta information. At a minimum a column giving the mass of each peak and a column giving molecular formulae or columns giving elemental counts must be present.
character string specifying the name of the column containing a unique identifier for each module node in e_data and e_meta.
character string specifying the name of the column containing the sample identifiers in f_data.
character string specifying the name of the column containing the module identifiers in e_meta.
character string specifying the name of the column containing the module node identifiers in e_meta
character string giving the type of FT-MS instrument data was generated by. Valid options are: "12T" and "21T". Defaults to "12T". This information is used to determine appropriate plotting functions for Van Krevelen, Kendrick, etc. plots.
character string specifying the database from which reaction information is drawn
further arguments
as.moduleData constructs a moduleData object which is an ftmsData object where the rows of e_data correspond to unique module nodes.
