粘贴的替代功能 [英] Alternative function to paste

问题描述

是否有可以替代粘贴的功能？
我想知道在R中是否存在这样的情况：

Is there a function that can be an alternative to paste ? I would like to know if something like this exists in R:

> buildString ( "Hi {1}, Have a very nice {2} ! " , c("Tom", "day") )

推荐答案

frankc和DWin是正确的，可以指向 sprintf（）。如果由于某种原因，您的替换零件实际上将以矢量的形式出现（即 c（Tom，day）） / code>），您可以使用 do.call（）将它们传递给 sprintf（） ：

If for some reason your replacement parts really will be in the form of a vector (i.e. c("Tom", "day")), you can use do.call() to pass them in to sprintf():

string <- "Hi %s, Have a really nice %s!"
vals   <- c("Tom", "day")

do.call(sprintf, as.list(c(string, vals)))
# [1] "Hi Tom, Have a really nice day!"
