In misasa/chelyabinsk: Express geochemical datasets

Description Usage Arguments Value See Also Examples

Read a session stored as a series of IONML. As of January 5, 2017, this function uses ‘ionml.read.laicpqms’ to read the IONML.

ionml.read.session(ionml.xml, t0 = 5, t1 = 20, t2 = 25, t3 = 60,
  ref = "Si29", error = "sterr", intensityp = FALSE,
  verbose = FALSE, ionml = TRUE)

`ionml.xml`	Paths to IONML.
`t0`	When baseline starts (default: 5 s, scalar or vector)
`t1`	When baseline ends (default: 20 s, scalar or vector).
`t2`	When ion starts (default: 25 s, scalar or vector).
`t3`	When ion ends (default: 60 s, scalar or vector).
`ref`	Reference ion such as ‘Si29’.
`error`	Use ‘sterr’, ‘DL’, or ‘mix’ as error. When ‘mix’, error is delection limit ‘DL’ instead of standard error ‘sderr’ when DL is larger than ‘sderr’.
`intensityp`	Have mean and sd of intensity instead of mean and sderr of ionic ratio
`verbose`	Output debug info (default: FALSE).
`ionml`	Read IONML file instead of IONCSV (default: TRUE).

Pseudo-pmlame with average and standard error of ionic ratio
