Well Jia, you use 'all' as a name for your dataframe, but this is also a
function, see ?all. If I try it with
mydata - data.frame(z1,z2,z3)
all goes well.

Hi,
your matix has 5 rows and 6 columns. So, either you do
ind - 1:5
res[,1] - ind
or

I do not fully understand your question but how about :

BTW, did you mean colnames(df) - paste(colnames(df), suffix) instead
of paste(df, suffix) ?
It's more a general point about having to write things out twice when
you do assignments. I could also have written:
data.frame[some.condition another.condition, big.list.of.columns] -
data.frame[some.condition another.condition, big.list.of.columns] * 2 + 55

Thanks for the solution. But my problem is still there. I have 500 company

2. colnames are just another vector, so do

z1 - m[m[,1] == 2,, drop=FALSE]
What is the problem you are trying to solve?
It was not really a big problem.
Just that without the drop argument,
The changing returned type complicated
the next computations.
drop=TRUE makes it homogeneous, which is what I needed.
Why create an enormous matrix? Why not read each company's info and
immediately write it to the file using write.csv( ... append = TRUE ...)?

Not sure about your data set, but if you have some kind of
(weighted/stratified) sample of hospitals you need to pay special
attention. Survey data violates the assumptions of the classical
linear models (infinite population, identically distributed errors
etc) and needs to be analyzed

After a little digging, it turns out that fit.mult.impute will allow
