[R] lapply() not converting columns to factors (no error message)

[Sundar Dorai-Raj]

Works for me:

x <- read.csv(url("http://dc170.4shared.com/download/153147281/a5c78386/Testvcomp10.csv?tsid=20091116-075223-c3093ab0"))
names(x)
x[2:13] <- lapply(x[2:13], factor)

> levels(x$P1L55)
[1] "0" "1"
> is.factor(x$P1L96)
[1] TRUE

> sessionInfo()
