001、par(mar）选项的作用是调整绘图区域距离外围框线的距离。作用和par(mai)一样， 可能只是单位不一样. par(mfrow = c(2, 2)) par(mar = c(1, 1, 1, 1)) plot(1:10, main = "mar = 1", cex.main = 3) box(which = "figure", lwd = 5) box(which = "plot", lwd = 5) par(mar
1、 完整代码： dat <- read.table("result.fst", header = T) head(dat) chrlen <- vector() for (i in unique(dat$CHR)) { temp <- dat[dat$CHR == i,] temp <- temp[order(temp[,3], decreasing = T),] chrlen <- c(chrlen, temp[,3][1]) }
