Subject: subset data right
Hi all,
I have the following df and I want to know which Protocols are VeryFast, which are FAST, which are SLOW and also which ones are VerySLOW :
$ Protocol : Factor w/ 48 levels "DP FS QTSE SAG",..: 5 5 28 5 5 5 7 7 47 5 ...
$ quant : Factor w/ 4 levels "FAST","SLOW",..: 2 2 2 4 2 1 1 2 4
I do the following subset but nothing is changed in my df:
subdf=subset(df,quant%in%c("VeryFast"))
subdf$quant=factor(subdf$quant)
and when I get the str(df) again Protocol has 48 levels. Does anyone know how can I get these subsets right?
Thanks for any help!
