HiI have a probability mass function similar to pr(N=n)=
integral(((2-x)^n)*(exp(ax-2))) - integral (((5-ax)^n)), both integrals are

After updating Java, I have to run R CMD javareconf. On Windows

version as it updates that wanted for 32-bit browsers. The 64-bit

Is there a way how to find out from within a .Rmd file what output format

The reason is this: I write a paper in R markdown in RStudio. Sometimes I
generate .html, sometimes .pdf. My paper presents a table of regression
models using stargazer function. I've got the following cod

Dear Charles,
How about the following?

This seems reasonably fast. For example:

Great!! It is perfect!
Thank you, John, for this elegant and fast suggestion!

One idea is to export to CSV and load it yourself.

Yes, markdown is not LaTex. However, RStudio run pandoc that can convert
markdown to HTML, LaTeX, Word, and many other markup (or almost markup)
languages. The conversion to the first three mentioned works automatically
in RStudio.
But you are right in one thing: perhaps it is not a matter of knit

Since both of you seem to have misinterpreted my response, consider the
following for clarification:
A <- matrix(1:1000, 1000, 10)
B <- A[1:100, ]
# my recommended solution
t1 <- system.time({match(as.data.frame(t(B)), as.data.frame(t(A)))})

I don't know your fut data, next time would help a simple dput(fut). Taking

Assuming that your data.frame() is called dd, the following should get you

This method handles cases where multiple columns are "Yes".
library(reshape2)
ddl <- melt( dd, id.vars = "PLTID" )
ddl[ is.na( ddl$value ), "value" ] <- ""
ddl <- ddl[ "Yes" == ddl$value, ]
