Topographical plot of a GCIMSSample object

# S4 method for GCIMSSample,ANY
plot(
  x,
  dt_range = NULL,
  rt_range = NULL,
  ...,
  remove_baseline = FALSE,
  trans = "cubic_root"
)

Arguments

x: A GCIMSSample object
dt_range: A numeric vector of length 2 with the drift time range to plot (in milliseconds)
rt_range: A numeric vector of length 2 with the retention time range to plot (in seconds)
...: Ignored
remove_baseline: Set to TRUE to subtract the estimated baseline first
trans: The transformation to the intensity values. "cubic_root" is the default. "intensity" is also valid. See the trans argument in ggplot2::continuous_scale() for other possibilities.

Value

A plot of the GCIMSSample

Examples

dummy_obj <-GCIMSSample(
  drift_time = 1:2,
  retention_time = 1:3,
  data = matrix(1:6, nrow = 2, ncol = 3),
  gc_column = "Optional column name",
  drift_gas = "nitrogen",
  drift_tube_length = 98.0 # in mm
)
plot(dummy_obj)
