[GRASSLIST:8095] Re: r.profile & subsequent chart plot

[Miha Staut]

Good plotting programmes are R or Gnuplot.
Example with the use of R:

GRASS 6.1.cvs (loc):~ > r.profile -i in=yourrast null="NA" > profile
> R   # start R
> profile <- read.table("profile", sep=" ", head=F)
> str(pr)
`data.frame':   439 obs. of  2 variables:
 $ V1: num  0 100 200 300 400 500 600 700 800 900 ...
 $ V2: int  NA NA NA NA NA NA NA NA NA NA ...
> plot(pr$V1,pr$V2,ty="l")

# If you wish to get height vs. length in equal scale use argument asp=1, e.g.
> plot(V1, V2, xlim = c(min(V1, na.rm=T), max(V1, na.rm=T)), ylim = c(min(V2,
na.rm=T), max(V2, na.rm=T)), asp = 1, ty = "l")
