[R] Variable which has the maximum value of DF

[Lauri Nikkinen]

Hi,

Suppose I have a data.frame like this

Lines <- "var1 var2 var3 var4 var5 var6

  0      2      1     2      0      0
  2      3      7     6      0      1
  1.5    4      9     9      6      0
  1.0    6      10    22     3      3
"
DF <- read.table(textConnection(Lines), skip=1)
names(DF) <- scan(textConnection(Lines), what = "", nlines = 1)

How do I find the name of the variable which has the maximum value of
the data.frame? In this example the answer is "var3" (22).

Best regards,
Lauri
