[R] int vector

[PIKAL Petr]

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

Petr
