Want to create empty vectors inside a empty data frame
Hi All,
I want to create empty vectors inside an empty data frame.The name of the
vectors has to come dynamically.
For example if record_mean is my empty data frame,and i have say 4
categories,the category names for record mean data frame has to
recmeanC1,recmeanC2,recmeanC3,recmeanC4,which will be dynamically created
and which will again be inserted in my data frame's as column values.Each of
these should be also vectors later.Because later i want to use the cbind
function.
I wanted to do this:--
record_mean<-cbind(recmeanC1,recmeanC2,recmeanC3,recmeanC4)
where:--
