[R] Sweave scientific real display format (e.g. 5e-12)

[Ken Knoblauch]

Oops,

the third line should have been:
xss<-unlist(strsplit(xc,""))
to get that output but I'm missing something about escaping the backslash,
since
it's missing and when I double it, it doubles.  I think that there has
been some
discussion about this on the list, if you look it up.

***********************************
How about some variation on the following:

x <- 5e-12
xc <- as.character(x)
xss<-strsplit(xc, "")
paste("$",xss[1],"\cdot ^{",xss[3],xss[4], xss[5],"}$", sep = "")
[1] "$5cdot ^{-12}$"

untried, of course, but maybe you could squeeze something out of it.

*********************************
Dear All,

I couldn't figure and couldn't google out how to make construct a pair of
\Sexpr s or a LaTeX macro that would include
      5\cdot 10^{-12}
into the LaTeX output istead of
      5e-12 .

Any ideas?

Thank you

Gábor
