我想设置模拟位置的坐标。我试图设置坐标,我也设置了权限,但我的位置没有改变。所以任何人都知道如何解决这个问题? 这是我的代码:

# setup
library(ggplot2)
library(plyr)
library(gridExtra)

trt      <- factor(rep(LETTERS[1:2],150),ordered=TRUE)
vis      <- factor(c(rep(1,150),rep(2,100),rep(3,50)),ordered=TRUE)
id       <- c(c(1:150),c(1:100),c(1:50))
val      <- rnorm(300)
data     <- data.frame(id,trt,vis,val)
base     <- with(subset(data,vis==1),data.frame(id,trt,baseval=val))
data     <- merge(data,base,by="id")
data     <- transform(data,chg=ifelse(vis==1,NA,val-baseval))
data.sum <- ddply(data, .(vis, trt), summarise, N=length(na.omit(val)))
data     <- merge(data,data.sum)
data     <- transform(data, trtN=paste(trt,N,sep="\n"))
mytheme  <- theme_bw() + theme(panel.margin = unit(0, "lines"), strip.background = element_blank())

# no missing facets
plot.a   <- ggplot(data) + geom_boxplot(aes(x=trtN,y=val,group=trt,colour=trt), show.legend=FALSE) +
            facet_wrap(~ vis, drop=FALSE, switch="x", nrow=1, scales="free_x") +
            labs(x="Visit") + mytheme
# first facet should be blank
plot.b   <- ggplot(data) + geom_boxplot(aes(x=trtN,y=chg,group=trt,colour=trt), show.legend=FALSE) +
            facet_wrap(~ vis, drop=FALSE, switch="x", nrow=1, scales="free_x") +
            labs(x="Visit") + mytheme

grid.arrange(plot.a,plot.b,nrow=2)

}
