Re: [R] create sequence of numbers
Hi Alex, Could you give us the values you used, by providing the output of: dput(CRagent[[1]]$xy[1]) dput(CRagent[[2]]$xy[1]) ?

Re: [R] create sequence of numbers
one way is to use the sign() function, e.g., a - 2 b - 3 seq(a, b, by = sign(b-a)*0.5) a - 3 b - 2 seq(a, b, by = sign(b-a)*0.5) I hope it helps.
