Constructs a new ftmsData object that is a subset of the original with only the specified samples or group. Exactly one of samples or group must be specified.

# S3 method for peakData
subset(x, samples = NA, groups = NA, check_rows = FALSE, ...)

subset(x, samples = NA, groups = NA, check_rows = FALSE, ...)

# S3 method for reactionData
subset(x, samples = NA, groups = NA, check_rows = FALSE, ...)

# S3 method for moduleData
subset(x, samples = NA, groups = NA, check_rows = FALSE, ...)
