函数名称在R中以图例形式评估为文本？

Question

I was wondering how I could have d in my R code below be used in legend ?

Note that the reason I don't use d = c("dnorm", "dcauchy") is that in my actual code I need to use d[[1]](0) which doesn't work with quotations.

plot(1)
d = c(dnorm, dcauchy)
legend("topleft", legend = d) ## HERE how can I have the two terms:
                              ## dnorm and dcauchy in `d` appear as legend?

If you wish to use the same list as both the names and the functions you can do this.

d = c("dnorm", "dcauchy")     # works for printing strings

And when you want to use it as a function write

get(d[[1]])(0)
[1] 0.3989423
