the vaccination schedule could have prevented most or all of the reported cases of
autism. Of the potential serious side effects of thimerosal (the mercury preservative
used in vaccines), most of the serious reactions reported to VAERS are secondary
complications of hepatitis B.... In the VAERS database, six other serious reactions
(pneumonitis, [a]septicemia, septic arthritis, peripheral polyneuropathy, and sensorimotor
neuropathy) were associated with the same product, which contained thimerosal, as
was reported to the manufacturer for the serious reaction. However, no serious
reactions related to thimerosal were reported for children under two years of age in
1998.... Based on the summary statistics in this report, the risk of adverse events
among children under 2 years of age (primary vaccinees) exposed to thimerosal-
containing vaccines is much less than the risk of adverse events among older
children and adults (nonprimary vaccinees) exposed to thimerosal-containing
vaccines.... Thus, we see no reason to change the present dosing schedule for
diphtheria, tetanus, acellular pertussis, hepatitis B and inactivated polio vaccines
which includes two doses of thimerosal-containing vaccines.

What do we know about the incidence and prevalence of autism in 1998?
The following is a summary of findings that are based on a survey of the
children reported to have been diagnosed with autism in 1998 (GAO-03-17A). This
summary is based on information in the 1998 National Survey of Children's Health

Selecting the variable in a loop, to use in a function
So I'm looping through the rows of a table (using the data.table package, but that's not really important) and in each row I'd like to get a number out of that row and append that number to a vector.
What I have so far is:
for(i in 1:nr.rows) {
print(the.matrix[i, ] # the name of the column)
# this is where I'm stuck
}
The reason for the loop is that the.matrix[i, ] is a multi-dimension matrix, and I need to extract a number from each row.
The output I'd like is something like this:
[1] 5.59405
[2] 8.61482
[3] 8.31273
And the reason I need that number is because I want to make an ANOVA, which requires all numbers to be of the same length.
Is there a way I can write a function to extract that number, because it's the same in all rows? Or is there another better way to get this done?
Thanks!
A:
I'm not really familiar with data.table, but from what I understand, you want to create a numeric vector with each element being the number you extracted from each row, isn't that it? If you want this done only once and stored somewhere, I'd suggest you to use list and assign it to an
