coordinates(A) <- c("x", "y")> gridded(A) <- TRUE> greenchannel<-matrix(A[,3],nrow=155,ncol=191,byrow=TRUE)Error in as.vector(x, mode) : cannot coerce to vectorredchannel<-matrix(A[,4],nrow=155,ncol=191,byrow=TRUE)Error in as.vector(x, mode) : cannot coerce to vector> nearinfraredchannel<-matrix(A[,5],nrow=155,ncol=191,byrow=TRUE)Error in `[.data.frame`(x@data, i, j, ..., drop = FALSE) :   undefined columns selected> midinfraredchannel<-matrix(A[,6],nrow=155,ncol=191,byrow=TRUE)Error in `[.data.frame`(x@data, i, j, ..., drop = FALSE) :   undefined columns selectedThe image plot was black background with x and y axis values.
