v1.1.1

isogeochem 1.1.1

Function updates

• d17O_c() now allows to choose from two different 17O/18O fractionation factors.

Minor improvements

• Reformatted NEWS.md

v1.1.0

isogeochem 1.1.0

Function updates

• a18_c_H2O(temp = 25, min = "dolomite", eq = "Muller19") Can now calculate the dolomite/water 18O/16O fractionation factor.
• a18_CO2acid_c(temp = 25, min = "dolomite") Can now calculate the dolomite/CO2 18O/16O AFF.
• a18...() functions now return meaningful errors.
• d17O_c(D17O_H2O = 0.025) Can now take into account a non-zero D17O value for the ambient water.
• mix_d17O(step = 20) was overhauled. It now allows D17O values as input and specifying the resolution of the output. The output of the function now returns the d17O values as the fourth element in the data frame.

New functions

• d17O_qz() to calculate equilibrium oxygen isotope values for quartz.

New dataset

• meteoric_waters is a compilation of d17O and d18O values for meteoric waters.

Misc

• Readme updates
• Vignette updates
• Description updates

• Added the "Kim07" eq to "aragonite" in a18_c_H2O()
• Added the "vanDijk18" eq to "siderite" in a18_c_H2O()
