Thanks everyone. John's original solution worked great. And with
27,000 records, 65 alarm.words, and 6 columns to search, it takes only
about 15 seconds. That is certainly adequate for my needs. But I
will try out the other strategies too.
And thanks also for lot's of new R things to
Hi Dawn,
Your data are a bit messed up, but try the following:
colSums(dat[,grep(ABC,names(dat),fixed=TRUE)],na.rm=TRUE)
colSums(dat[,grep(XYZ,names(dat),fixed=TRUE)],na.rm=TRUE)
I'm assuming that you want to discard the NA values.

Hi Phong,
This is a common problem with using color to represent numeric values.
What you want is a reference scale. Whenever you call color2D.matplot,
use the cellcolors argument to specify the colors of each cell. You
can directly call color.scale in this argument, using the xrange
argument of

Your LyX example has two problems: 1) We don't have your .RData; 2)
You didn't library(reshape) and library(lattice). Hence it is not a
self-contained reproducible example.
After fixing these two issues, I don't see why lattice graphics can be
problematic with knitr. There is no need to print()

I'd recommend starting with a simpler .Rmd or .Rnw file, rather than

Strictly speaking, the answer is yes because you can unroll the loop, but that
probably is not what you really want or need to do.
Your example seems about right, but it is not clear how you plan to make 44
conform with 5500.
What does it mean to unroll the loop?
Thanks!

Yes. This is one of the fundamental challenges in text searching --
defining exactly what text defines a match and what doesn't. So,
continuing your example, one might imagine that heroin and heroine
might both be matches, but maybe heroines shouldn't be (e.g. if the
text contains movie reviews).

Yes, assign() and get() can do this, but I think the [[]] syntax is simpler
and makes it easier to switch between lists and environments for
data organization.
E.g., the translation of
myData[[varName]][4] - myData[[varName]][4] * 100
where myData is an environment to the get/assign style
