I have a data frame created with this code:
require(reshape2)
foo <- data.frame( abs( cbind(rnorm(3),rnorm(3, mean=.8),rnorm(3, mean=.9),rnorm(3, mean=1))))
qux <- data.frame( abs( cbind(rnorm(3),rnorm(3, mean=.3),rnorm(3, mean=.4),rnorm(1, mean=2))))
bar <- data.frame( abs( cbind(rnorm(3,mean=.4),rnorm(3, mean=.3),rnorm(3, mean=.9),rnorm(3, mean=1))))
colnames(foo) <- c("w","x","y","z")
colnames(qux) <- c("w","x","y","z")
colnames(bar) <- c("w","x","y","z")
rownames(foo) <- c("n","q","r")
rownames(qux) <- c("n","q","r")
rownames(bar) <- c("n","q","r")
foo <- cbind(ID=rownames(foo),foo)
bar <- cbind(ID=rownames(bar),qux)
qux <- cbind(ID=rownames(bar),qux)
foo$fn <- "foo"
qux$fn <- "qux"
bar$fn <- "bar"
alldf<-rbind(foo,qux,bar)
alldf.m <- melt(alldf)
What I want to do is to create a ggplot
line curve in facet format, so it creates a graph like this:
The actual graph does not contain upward lines - this is just a sketch so that the line separation is clear.
My current code doesn't work:
library(ggplot2)
p <- ggplot(data=alldf.m, aes(x=variable)) +
geom_line(aes(colour=ID),alpha=0.4)
p <- p + facet_wrap( ~ fn)
p
What's the best way to do it?
Try this:
ggplot(data=alldf.m, aes(x=variable, y = value, colour = ID, group = ID)) +
geom_line() + facet_wrap(~fn)
