Replace a variable by its value
I have a dataset called "raw-data" . I am trying to use the following code -
col_name<-names(raw_data)
for (i in 1:(length(names(raw_data))-2))
{
tbl=table(raw_data$Pay.Late.Dummy, raw_data$col_name[i])
chisqtest<-chisq.test(tbl)
}
Say the 1st column of my raw_data is Column1. The idea is when i=1 then
raw_data$col_name[i] will automatically become raw_data$Column1 ,

how to skip a numeric column for averaging other columns?
Data has the first row for variable name and the first column for sample
name. I want to take "Log" for all data, but how to compute without the
first column for sample name.
That is,
column 1: sample ID
column 2-10: data
I want to find an average on each column (2-10)

I do have two different time series A and B, they are different in length and starting point. A starts in Jan, 2012 and ends in Dec, 2012 and B starts in March, 2012 and ends in Nov, 2012.
