Turn the intensity matrix into a data frame

Turn the intensity matrix into a data frame

# S3 method for GCIMSSample
as.data.frame(
  x,
  row.names = NULL,
  optional = FALSE,
  dt_range = NULL,
  rt_range = NULL,
  dt_idx = NULL,
  rt_idx = NULL,
  ...
)

Arguments

x

A GCIMSSample object

row.names

NULL or a character vector giving the row names for the data frame. Missing values are not allowed.

optional

logical. If TRUE, setting row names and converting column names (to syntactic names: see make.names) is optional. Note that all of R's base package as.data.frame() methods use optional only for column names treatment, basically with the meaning of data.frame(*, check.names = !optional). See also the make.names argument of the matrix method.

dt_range

The minimum and maximum drift times to extract (length 2 vector)

rt_range

The minimum and maximum retention times to extract (length 2 vector)

dt_idx

A numeric vector with the drift time indices to extract (or a logical vector of the length of drift time)

rt_idx

A numeric vector with the retention time indices to extract (or a logical vector of the length of retention time)

...

unused

Value

A data frame with dt_ms, rt_s and Intensity columns
