有没有办法去抖动的线geom_line()
我知道这有点违背了这一阴谋的目的,但如果你有几行情节,并希望他们都表现出它可能是得心应手。 也许一些其他的解决这个问题的可视性 。
请参阅下面的代码,
A <- c(1,2,3,5,1)
B <- c(3,4,1,2,3)
id <- 1:5
df <- data.frame(id, A, B)
# install.packages(reshape2)
require(reshape2) # for melt
dfm <- melt(df, id=c("id"))
# install.packages(ggplot2)
require(ggplot2)
p1 <- ggplot(data = dfm, aes(x = variable, y = value, group = id,
color= as.factor(id))) + geom_line() + labs(x = "id # 1 is hardly
visible as it is covered by id # 5") + scale_colour_manual(values =
c('red','blue', 'green', 'yellow', 'black'))
p2 <- ggplot(subset(dfm, id != 5), aes(x = variable, y = value,
group = id, color= as.factor(id))) + geom_line() + labs(x = "id #
5 removed, id # 1 is visible") + scale_colour_manual(values =
c('red','blue', 'green', 'yellow', 'black'))
# install.packages(RODBC)
require(gridExtra)
grid.arrange(p1, p2)
