Hi Rich,
I’m not doing the same thing as Hmisc::latex(). That generates a .tex file and
compiles it (or at least it appears to try to do that on my system, but it
stopped partway through for me).
When I ran
Hmisc::latex(a~b)
It generated a .tex file for a table:
\begin{table}[!tbp]
\begin{center}
\begin{tabular}{l}
\hline\hline
\multicolumn{1}{c}{}\tabularnewline
\hline
~\tabularnewline
a\tabularnewline
b\tabularnewline
\hline
\end{tabular}\end{center}
\end{table}
While I’m wanting an equation:
$$a = b$$
Thanks,
Bill

Please be consistent with the latex() function in the Hmisc package. For
example, for an array x, latex (x) produces a complete latex table environment.
See the ?latex helpfile for details.

Hello,
I'm working on a function in a package that will provide an exported
function that will convert formula to LaTeX equations. For that, it
recursively goes through the formula converting objects of class "formula",
"call", "name", and "(" to LaTeX.
I have a private S3 generic function that I'm using for the conversion, but
for some reason, the generic is not detected, and checking the package fails
for that reason
(https://travis-ci.org/billdenney/bsd.report/jobs/651510333):
no applicable method for 'knit_print_helper_formula' applied to an object of
class "name"
Backtrace:
1. testthat::expect_equal(...)
4. bsd.report:::knit_print.formula(a ~ b(c))
6. bsd.report:::knit_print_helper_formula.formula(x, ..., replacements =
replacements)
9. bsd.report:::knit_print_helper_formula.call(x[[3]], ...)
10. bsd.report:::knit_print_helper_formula.function_call(x, ...)
11. base::sapply(...)
12. base::lapply(X = X, FUN = FUN, ...)
13. bsd.report:::FUN(X[[i]], ...)
But, there is a knit_print_helper_formula.name
<http://knit_print_helper_formula.name> function call defined
(https://github.com/billdenney/bsd.report/blob/master/R/knit_print.formula.R
<https://github.com/billdenney/bsd.report/blob/master/R/knit_print.formula.R#L60-L79>
#L60-L79):
knit_print_helper_formula <- function(x, ...) {
UseMethod("knit_print_helper_formula")
}
# Some other methods
knit_print_helper_formula.name <http://knit_print_helper_formula.name> <-
function(x, ...) {
# Function body
}
Does anyone know why the S3 method for name class objects is not found when
checking the package?
Thanks,
Bill
