paleoxrf

The goal of paleoxrf is to simplify reading data from Acadia's paleoenvironmental X-Ray Fluorescence laboratory.

Installation

You can install paleoxrf from GitHub using the following code:

# install.packages("remotes")
remotes::install_github("paleolimbot/paleoxrf")

If all is well, you should be able to load the package:

library(paleoxrf)

The examples below use dplyr to manipulate the output of the read functions.

library(dplyr)

Reading XRF Data

The package provides a few functions to read XRF data output from several types of machines, such as the Olympus Vanta. The function reads the raw output of the machines, rather than a "cleaned up" version from other spreadsheet software.

test_file_oly <- system.file(
  "xrf_files/olympus_vanta_test.csv", 
  package = "paleoxrf"
)

read_olympus_vanta(test_file_oly) %>%
  select(date_time, sample_id, ends_with("_conc"))

test_file_pan <- system.file(
  "xrf_files/panalytical_test.txt", 
  package = "paleoxrf"
)

read_panalytical_txt(test_file_pan) %>%
  select(date_time, sample_id, ends_with("_conc"))
