This is just a curiosity question. Why do the two
different syntaxes for df1 and df2 give such different
results in the names(dfx)?
Thanks
df1 <- data.frame(nas = c("A", "B" , "B" ,"C" ,"B",
"A", "D"),nums = c(3, 2, 1, 1, 2, 3, 7))
df2 <- data.frame(nas <- c("A", "B" , "B" ,"C" ,"B",
"A", "D"),nums <- c(3, 2, 1, 1, 2, 3,
7))
df1; df2
>df1
nas nums
1 A 3
2 B 2
. .
> df2
nas....c..A....B....B....C....B....A....D..
nums....c.3..2..1..1..2..3..7.
1 A
3
2 B
3
