Combine linearmask Objects
Form a new linearmask object by combining the underlying vertices and drawing a new systematic sample.
## S3 method for class 'linearmask' rbind(..., cleanskips = TRUE)
... |
one or more linearmask objects with the same spacing |
cleanskips |
logical; passed to internal function |
The maptools function spRbind is used to combine the
‘SLDF’ attributes of the inputs.
If the input objects have a ‘graph’ attribute then a new graph will be included in the output.

x <- seq(0, 4*pi, length = 200) xy <- data.frame(x = x*100, y = sin(x)*300) xy2 <- data.frame(x = x*100, y = cos(x)*300) test <- read.linearmask(data = xy, spacing = 20) test2 <- read.linearmask(data = xy2, spacing = 20) plot(rbind(test, test2))
