I have a data frame with one column "x":
> str(data)
`data.frame': 20 obs. of 1 variable:
$ x: num 0.0495 0.0986 0.9662 0.7501 0.8621 ...
Normally, I know that the notation dataframe[indexes,] gives you a new
data frame which is the specified set of rows. But I find:
> str(data[1:10,])
num [1:10] 0.0495 0.0986 0.9662 0.7501 0.8621 ...
Here, it looks like the operation
data[1:10,]
has converted it from type data frame into a numeric vector. Why does
this happen, and what can I do about it?
