why does data frame subset return vector
...tes a vector rather than a data frame whereas sub-setting the 2 column data frame returns a new data frame (as I'd expect). > df.rr[1:4,] [1] 1.11e-16 1.11e-16 1.11e-16 1.11e-16 > is.vector(df.rr[1:4,]) [1] TRUE > is.data.frame(df.rr[1:4,]) [1] FALSE > df.rr <- read.table("CLO_RR_anova.txt", header=T, comment.char="") > is.data.frame(df.rr[1:4,]) [1] TRUE Any explanation is appreciated. There must be a good reason for this I guess ... . On the other hand is there a way to fore the subset of the 1 colum data frame to be dataframe itself? I'd just like to see...
