Hi
data, data, data. Use dput(head(data,10)) if the data frame is too big.
zdrz <- structure(list(sklon = c(10, 10, 10, 10, 20, 20, 20, 20, 20,
40, 40, 40, 40, 95, 95), ot = c(0.8, 1.5, 4, 10, 15, 1.5, 4,
10, 15, 1.5, 4, 10, 15, 4, 15), doba = c(140, 111, 42.8, 20.3,
15, 88, 38.25, 17.33333333, 12.5, 65.16666667, 27, 12.5, 9.166666667,
15.75, 5.883333333)), .Names = c("sklon", "ot", "doba"), row.names = c(NA,
15L), class = "data.frame")
> sapply(zdrz, class)
sklon ot doba
"integer" "numeric" "numeric"
> dotchart(zdrz$sklon)
> fix(zdrz)
> sapply(zdrz, class)
sklon ot doba
"numeric" "numeric" "numeric"
> dotchart(zdrz$sklon)
fix changes column class to numeric but dotchart looks same to me
