Dear R help group: I am attempting to produce a density plot from a list of
20000 values using the density.lf function and would appreciate any help, I
hope I have done my homework reading the documentation but I still seem to
be missing something basic.
I have read the data as a table using read.table, with header=TRUE (I
excluded 2000 values), when calling the objects it appears to be there and
I can see the values
this is what I get when doing
density.lf (x=logN0, n=50, window="gaussian")
Error in `[.data.frame`(x, order(x, na.last = na.last, decreasing =
decreasing)) :
undefined columns selected
then assigned a column name (using colname so it is called first), then
assigned it as a vector using
assign ("x", c (logN0))
the error I get is
density.lf (x, n=50, window="gaussian")
Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) :
'x' must be atomic
the traceback produces:
> traceback ()
5: stop("'x' must be atomic")
4: sort.int(x, na.last = na.last, decreasing = decreasing, ...)
3: sort.default(x)
2: sort(x)
1: density.lf(x, n = 50, window = "gaussian")
Thanks in advance, Andrea
