to_percent_change: Convert decimals difference to percent differences.

In tbadams45/wrviz: Create Vizualizations For Water Resources

Description

Converts a list of decimal numbers (e.g. 0.7, 1.0, 1.3) to their corresponding percent difference representation. The representation will depend on what value is selected as the baseline, i.e. 0% percent change.

Usage

to_percent_change(decimal_list, baseline = 1)

Arguments

decimal_list	The list to convert.
baseline	The value that represents 0% percent change.

Details

This function uses round() to avoid any weird floating point representation errors. Because of this, the best precision you can obtain is integers for your percent differences (e.g. can only get "52

Value

A list of the same length as decimal_list.

Examples

## Not run: to_percent_change(seq(0.5,1.5,by=0.1))
to_percent_change(seq(-0.3,0.7,by=0.1),baseline=0)
to_percent_change(seq(0.512,1.512,by=0.1)) # answer is rounded
## End(Not run)
