我正在尝试使用水平线制作绘图,其中 data2 和 data3 点应在 data1 范围内。这将给出不同颜色的重叠线,但我收到一条错误消息:
Error in strsplit(filename, "\\.") : non-character argument
这是数据和代码。请给我一些建议。
data1 <- data.frame(Start=c(10),End=c(19))
data2 <- data.frame(Start=c(5),End=c(15))
data3 <- data.frame(Start=c(6),End=c(18))
filter_data2 <- data2[data2$Start >= (data1$Start-(data1$Start/2)) & data2$End <= (data1$End+(data1$End/2)), ]
filter_data3 <- data3[data3$Start >= (data1$Start-(data1$Start/2)) & data3$End <= (data1$End+(data1$End/2)), ]
data1 <- data.frame(rep(1,nrow(data1)),data1)
colnames(data1) <- c("ID","start","end")
data2 <- data.frame(rep(2,nrow(filter_data2)),filter_data2)
colnames(data2) <- c("ID","start","end")
data3 <- data.frame(rep(3,nrow(filter_data3)),filter_data3)
colnames(data3) <- c("ID","start","end")
dat1 <- rbind(data1,data2,data3)
pdf("overlap.pdf")
p <- ggplot(dat1, aes(x=(max(start)-max(start)/2), y = ID, colour=ID))
p <- p + geom_segment(aes(xend =(max(end)+max(end)/2), ystart = ID, yend = ID))
p <- p + scale_colour_brewer(palette = "Set1")
ggsave(p)
