# sqrTICXY: Tick marks for Square plot In GEOmap: Topographic and Geologic Mapping

## Description

Lat-Lon Tick marks and grid for Square plot

## Usage

 1 2 3 sqrTICXY(prsurf, proj, side = c(1, 2, 3, 4), PMAT=NULL, LLgrid = TRUE, col = "black", colt = "black", font=5, cex=1, lty=2, lwd=1, pcex=1, TICS=NULL)

## Arguments

 prsurf list with x, y proj projection side vector, which sides to plot, 1=bottom, 2=left, 3=top, 4=right PMAT projection matrix from persp LLgrid logical, whether to add grid col color for grid colt color for text font default=2, font for labels cex character expansion for tic labels lty Line type for lines, default=2 lwd Line width for lines, default=1 pcex character expansion for tics, pch=2 TICS list(lat, lon) this will replace the default

## Value
