Hi, The error message,
Error in grid[i] <- x + (i - 1) * (y - x)/m : object of type 'closure' is not subsettable indicates that "grid" is actually known to R as a function (type grid to see its definition). You can define your own variable with the same name, but that needs to be done before the assignment in the for loop, ReturnsGrid = function(x,y,m){ grid <- vector(length = m) for (i in 1:m){ grid[i] <- x + (i-1)*(y-x)/m } grid } ReturnsGrid(0,9,3) HTH, baptiste 2009/11/27 Anastasia <nast...@gmail.com>: > Hello, > > I am new to R program, therefore, I am sorry if this is a really stupid > question. > I wrote a simple function and for some reason it doesn't work > > ReturnsGrid = function(x,y,m){ > for (i in 1:m){ > grid[i] <- x + (i-1)*(y-x)/m > } > grid > } > > xx=ReturnsGrid(0,9,3) > > Thanks a lot! > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
