Let's say I have a package that consists of a set of functions, fig1(),
fig2(), fig3() ..., each of which
produces a plot, and perhaps some printed output, e.g.,
fig1 <- function() plot(1:10)
fig2 <- function() plot(10:1)
fig3 <- function() {y<-sample(1:10,10); plot(y); y}
I'd like to produce a document (PDF or HTML) containing the listing of
each function and its output,
using knittr.
I can execute a list of figures using something like
# print and run a figure function
onefig <- function(fig) {
cat("Figure:") # how to get name of fig function?
print(fig)
fig()
}
lapply(list(fig1, fig2, fig3), onefig)
But I need to work with the names of the figure functions instead,
something like
figlist <- paste0("fig", 1:3)
# using figure name
onefig2 <- function(fig) {
cat("Figure:", fig, "\n")
print(body(fig))
eval(parse((paste0(fig,'()')))) # doesn't work
}
As well, I need to be able to find all functions in the package
namespace matching a pattern.
Can someone help?
