rot: Rotate model data frame X and Y coordinates to global...

In dpphat/MFtools: This is a package for reading MODFLOW and MT3DMS files

Description

This function reads in a MFtools data frame (i.e., from readdis, readbtn) that contains X and Y coordinates and converts those coordinates to a global coordinate system.

Usage

rot(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 (i.e., dis$BOT)
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

Examples

d <- readdis(rnm)
d$BOT %>% rot(X_off = 2970450, Y_off = 1926010, ROT = -45)
