Thank you for the suggestion
What seems to work is assigning out_put$Case - Inp_dat$Case
that is
for(i in 1:4)
{
...
Case- Inp_dat$Case[i]
…
out_put[i,]-data.frame(Case, stdL, stdPP, stdSE, L, PP, PP_SE)
}
out_put$Case - Inp_dat$Case
out_put
What I don't understand is
Apologies I was trying to simplify the programme and missed out four input
files. The files on Andrew, Burt, Charlie and Dave have the same format of
one factor and 13 numeric variables with repeated measurements eg.
Study v1 v2 v3 v4 v5 v6 v7 v8 v9
I am trying to incrementally add rows to an empty data frame. The data has 7
columns, the last 6 are numeric.
For the first columns I would like to include a text identifier, called
‘Case’ like Andrew, Burt, Charlie etc. that is also output to a data frame –
this is where I am having the problem

Inp_dat- read.csv(/File/Input data.csv)
out_put[i,]-data.frame(Case, stdL, stdPP, stdSE, L, PP, PP_SE)
These two statements look like the source of the problem.
Add the optional argument
stringsAsFactors=FALSE
to both.
