I forgot there is also ?mode.
mode(c(1,"2")) # "character"
mode(d.f$C)# "numeric" (not "integer")

Hello,
A way to see this is with ?class
# OP's code
typeof(c(1,"2")) # "character"
d.f <- data.frame(C=c(1,"2"))
typeof(d.f$C)# "integer"
# And check the objects' classes
class(c(1,"2")) # "character"
class(d.f$C)# "factor"
Hope this helps,

I think your character vector got converted to a factor. See ?options,
section stringsAsFactors:
‘stringsAsFactors’: The default setting for arguments of
‘data.frame’ and ‘read.table’.
The default is TRUE, so strings get converted to factors when building
data frames.
Set options(s
