Dear expeRts,
I know I can't paste expressions in the normal way, but I just
couldn't figure out
how to get the following (I want to paste a character vector to an
expression vector)
right with bquote() or substitute.
vec1 <- c("a", expression(tilde(b)), "c")
vec2 <- c("1", "2", "3")
main <- as.expression(paste(vec1, vec2))
plot(0,0, main=main[2])
Do not use `paste` ... it coerces your expression to a character value ... use `c` instead: > main <- as.expression(c(vec1, vec2)) > plot(1,1, main=main[2]) And then, even the as.expression is superfluous: > main <- c(vec1, vec2) > plot(1,1, main=main[2])
