Question

例如链接：“ http://stats.espncricinfo.com/ci/engine/player/219889.html?class=1;spanmin1=01+Jan+2011;spanval1=span;template=results;type=batting;view=innings”

我想使用向量替换上述链接的数值（219889），以获得不同的链接。

library(XML)
library(RCurl)

players = c(4578,272279,7133)

for (i in players) {
  read = HYPERLINK(CONCATENATE("http://stats.espncricinfo.com/ci/engine/player/",players[i],".html?class=1;spanmin1=01+Jan+2011;spanval1=span;template=results;type=batting;view=innings"))
}

Answer 1

将sprintf与%s或%d一起使用

sprintf("http://stats.espncricinfo.com/ci/engine/player/%s.html?class=1;spanmin1=01+Jan+2011;spanval1=span;template=results;type=batting;view=innings",players)

或paste0

paste0("http://stats.espncricinfo.com/ci/engine/player/", players, ".html?class=1;spanmin1=01+Jan+2011;spanval1=span;template=results;type=batting;view=innings")

如何使用向量替换链接的数值？
