这里是我的问题:
#data 1:
lab1 <- 1:10
group <- rep(1:3, each = length (lab1))
label <- rep(lab1, 3)
avar <- rep(c(0, 1, 4, 5, 6, 8, 10, 11, 12, 13), 3)
myd <- data.frame (group, label, avar)
# data 2
fillcol <- rep(rnorm(length(lab1)-1, 0.5, 0.2), 3)
group1 <- rep(1:3, each = length(fillcol)/3)
# this variable will be used to fill color in bars
filld <- data.frame(group1, fillcol)
# now plotting
par(mfrow = c(3, 1))
par(mar = c(2.5, 1, 2.5, 1))
#plot1
myd1 <- myd[myd$group ==1,]
filld1 <- filld[filld$group1 ==1,]
blues <- colorRampPalette(c("yellow", "blue"))
barplot(as.matrix(diff(myd1$avar)), horiz=T, col=blues(10)[10* filld1$fillcol],
axes=F, xlab="Mark")
axis(1, labels=myd$label, at=myd$avar)
axis(3, labels=myd$avar, at=myd$avar)
虽然这个样本数据集,我有很多变数,我想这个过程自动化。
for (i in 1:length(unique(myd$group))){
par(mfrow = c(i, 1))
par(mar = c(2.5, 1, 2.5, 1))
myd[i] <- myd[myd$group ==i,]
filld[i] <- filld[filld$group1 ==i,]
blues <- colorRampPalette(c("yellow", "blue"))
barplot(as.matrix(diff(myd[i]$avar)), horiz=T,
col=blues(10)[10* filld1$fillcol], axes=F, xlab="Mark")
axis(1, labels=myd[i]$label, at=myd[i]$avar)
axis(3, labels=myd[i]$avar, at=myd[i]$avar)
}
Error in dim(data) <- dim : attempt to set an attribute on NULL
In addition: Warning messages:
1: In `[<-.data.frame`(`*tmp*`, i, value = list(group = c(1L, 1L, 1L, :
provided 3 variables to replace 1 variables
2: In `[<-.data.frame`(`*tmp*`, i, value = list(group1 = c(1L, 1L, :
provided 2 variables to replace 1 variables
编辑:我想,这样我创建循环中的多个图形创建一个循环:
PS:我是新来的R和计算器。 请原谅我,如果这个问题是不恰当的,虽然我读的指导方针,并尝试坚持下去
