r plot main，R plot 主选项中的迭代器

Question

我需要一种方法来用它的迭代器 "i" 来更改主图，例如 main = "Grafico de credibilidad" + i，然后当 6 个图出现时，它们的标题会更改为 "Grafico de credibilidad 1" 和 1 增加。

momentos1 <- read.table("momentos1.txt")
par(mfrow = c(2,3),bg = "white") 
x<-seq(0,1,0.01) 

for(i in 1:6){
  plot(x,dbeta(x,momentos1$alpha.1.30.[i],momentos1$beta.1.30.[i]),
       main = "Grafico Credibilidad",axes = F,col="blue",
       ylab = "",
       xlab = "",
       ylim = c(0,5),type = "l"
       )
  axis(1,at = seq(0,1,0.1),las=1)
  box()
  grid()
}

非常感谢。

Answer 1

您可以使用paste()

momentos1 <- read.table("momentos1.txt")
par(mfrow = c(2,3),bg = "white") 
x<-seq(0,1,0.01) 

for(i in 1:6){
  plot(x,dbeta(x,momentos1$alpha.1.30.[i],momentos1$beta.1.30.[i]),
       main = paste("Grafico Credibilidad ",i),axes = F,col="blue",
       ylab = "",
       xlab = "",
       ylim = c(0,5),type = "l"
       )
  axis(1,at = seq(0,1,0.1),las=1)
  box()
  grid()
}
