rot2mod: Rotate global coordinates in a data frame to model...

Description Usage Arguments Examples

Description

This function reads in a data frame that contains X and Y coordinates and converts those coordinates to a model coordinate system (i.e., zero rotation and X_off = Y_off = 0).

Usage

1
rot2mod(df, X_off = 0, Y_off = 0, ROT = 0, Xin = X, Yin = Y)

Arguments

df

This is the data frame containing the X and Y coordinates

X_off

This is the global X coordinate offset

Y_off

This is the global Y coordinate offset

ROT

This is the rotation angle in units of degrees

Xin

This is the dataframe column containing the X coordinate location

Yin

This is the dataframe column containing the Y coordinate location
