as.numeric : what goes wrong?
I have a character vector j1 created from dimnames and want it to convert it
to numeric.
Like the first element:
> j1[1]
f896
1 896
> as.numeric(j1[1])
[1] 1990
why is it not 896 as it should be?
This is true fr the whole vector.
Thanks
W.P.

Anomaly in sample() function
...from partition 2 (type) which I use to check
for representativeness, deviates up to 20 percentage points from the
population.
As criterion I have computed the mean difference and the SD of the relative
frequencies between sample and pop. What mean deviation is to expect?
Thanks for any ideas,
