renaming_fa: Rename fatty acid variables from PROMISE into scientific...

In lwjohnst86/PROMISE.misc: Miscellaneous Helper Functions for the PROMISE Cohort

Description

Fatty acids in the PROMISE cohort are in the form e.g. ne160. In the typical data analysis pipeline, these variables may be converted into a long format such that these variables are now rows in a column. These variables will likely end up in plot, so it's necessary to convert them into the appropriate scientific format (e.g. NE 16:0, or such simply 16:0).

Usage

renaming_fa(fa, keep.fraction = TRUE)

extract_fa_fraction(x, uppercase = FALSE)

Arguments

keep.fraction	Logical. Whether to keep the fraction abbreviation as a prefix.
x	Vector (or column when through dplyr::mutate) of the original fatty acid names.
uppercase	Logical. Whether to convert the fraction abbreviation to upper case.

Value

Reformatted fatty acid names to be scientifically accurate.

Functions

• extract_fa_fraction: Extract the fatty acid fraction from the PROMISE fatty acid variables.

Examples

fattyacids <- c("ne160", "tg141n7", "TotalTG")
renaming_fa(fattyacids)
renaming_fa(fattyacids, keep.fraction = FALSE)
extract_fa_fraction(fattyacids)
extract_fa_fraction(fattyacids, uppercase = TRUE)
