我想这就是你想要的。
library(ggplot2)
library(reshape2)
# Fake some data
set.seed(1234)
nc <- 15
nr <- 20
onms <- sprintf("Observation%d",1:nr)
pnms <- sprintf("Prediction%d",1:nr)
cnames <- sprintf("x%d",1:nc)
odf <- data.frame(Observations=onms)
pdf <- data.frame(Predictions=pnms)
for(i in 1:nc){
vk1 <- 0.01*rnorm(nr)
odf[[cnames[i]]] <- round(cumsum(vk1),3)
vk2 <- 0.02*rnorm(nr)
pdf[[cnames[i]]] <- round(cumsum(vk1) + cumsum(vk2),3)
}
# This is the data we need
head(odf)
head(pdf)
# Now change the pred. colnames so they don't collide with the obs. colnames
newpnames <- sprintf("p_x%d",1:nc)
names(pdf) <- c("series",newpnames)
names(odf)[1] <- "series"
# Merge the data into a long format
modf <- melt(odf,id.vars="series",measure.vars=cnames)
mpdf <- melt(pdf,id.vars="series",measure.vars=newpnames)
mdf <- rbind(modf,mpdf)
# Now extract the fields we need into new columns
mdf$x <- as.numeric(gsub(".*[A-Za-z]","",mdf$variable))
mdf$frame <- as.numeric(gsub(".*[A-Za-z]","",mdf$series))
frameNames <- sprintf("Frame:%d",1:max(mdf$frame))
mdf$frame <- factor(sprintf("Frame:%d",mdf$frame),levels=frameNames)
mdf$kind <- substr(mdf$series,1,3)
# Finally plot it
ggplot(mdf) + geom_line(aes(x=x,y=value,color=kind)) + facet_wrap( ~ frame )
# ecdf version
ggplot(mdf,aes(x=value,color=kind)) + stat_ecdf(geom="step") + facet_wrap( ~ frame )
请注意,head
我伪造数据后的陈述给了你这个,所以这接近你从我相信的开始:
