Hello, I am plotting ordered data as a bargraph using the following code: bargraph.CI(response=yfac, x.factor=xfac, err.lty=0, data=test) However, I still get error bars. In fact, err.lty=*1* or *2* or *asd *gives the same results and no error massage even if left blank. err.col also produces no differences in the graph, but err.width does work. Am I doing something incorrectly or is this a bug? data segment: ID xfac yfac I3A 1 4 I7A 1 6 I4A 1 7 I13C 8 1 I13D 8 7 J2A 1 2 J10A 1 6 J5A 1 7 J8A 1 7 J7A 1 7 J16D 8 1 J16A 8 1 J13C 8 2 J15A 8 2 J16A 8 3 J14C 8 7 J14B 8 7 J18C 32 2 J19A 32 2 J17C 32 4 J17A 32 5 Sincerely, Nadia [[alternative HTML version deleted]]
