[R] Splitting the string at the last sub-string

[Tuszynski, Jaroslaw W.]

Hi,

I need to split a string into 2 strings, with the split point defined by the
last occurrence of some substring. I come up with some convoluted code to do
so:

str = "Chance favors the prepared mind"
sub = "e"
y = unlist(strsplit(str,sub))
z = cbind(paste(y[-length(y)], sub,  sep="", collapse = ""), y[length(y)]);

y
z
z[1]
z[2]

Is there a simpler way to do so? I think ~8 function calls to do such a
simple operation is an overkill.
