it looks to me that the names are cranked through make.names for
data frames case while that doesn't happen for matrices. Peeking
into the `colnames<-` code supports this idea, but that in turn
uses `names<-` which is a primitive and so defies further easy
peeking.
The data.frame function
Hi,
data.frame() checks names by default to ensure that column names are
legal, but there's an argument to change that.
>From ?data.frame()
check.names: logical. If ‘TRUE’ then the names of the variables in the
data frame are checked to ensure that they are syntactically

rm(list=ls()) is a bad practice... especially when posting examples. It doesn't
clean out everything and it removes objects created by the user.
Read ?data.frame, particularly regarding the check.names parameter. The intent
is to make it easier to use DF$A notation, though DF$`(A)` is usable if

Hello,
I am working with S-plus TimeSeries Object. I wonder how can I change the
column names of the variable instead of using the one default?
i.e to change DEV.MSCI to other name
PositionsDEV.MSCI

05/31/1980 00:00:00.000
Is this what you are looking for:
