[R] Variable which has the maximum value of DF
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 1.54 9 9 6 0 1.06 1022 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).

Perhaps, names(which.max(sapply(DF, max))) On 15/10/2007, Lauri Nikkinen [EMAIL PROTECTED] wrote: 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 1.54 9 9 6 0 1.06 1022 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?

I was thinking along the lines of M - as.matrix(DF) colnames(M)[col(M)[which.max(M)]] On 15/10/2007, Lauri Nikkinen [EMAIL PROTECTED] wrote: 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 1.54 9 9 6 0 1.06 1022 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?
