I have uploaded a raster file and polyline shapefile into R and use the extract
function to to extract the data from every pixel along the polyline. How do I turn the list output by extract
into a CSV file?
If I understand what it is you're asking, I think you could resolve your situation by using unlist().
d <- c(1:10) # creates a sample data frame to use
d <- as.list(d) # converts the data frame into a list
d <- unlist(d) # converts the list into a vector
