smartAlign2: Adjust positions of rectanglar shapes

In zhongmicai/complexHeatmap: Make Complex Heatmaps

Description

Adjust positions of rectanglar shapes

Usage

smartAlign2(start, end, range, range_fixed = TRUE)

Arguments

start	position which corresponds to the start (bottom or left) of the rectangle-shapes.
end	position which corresponds to the end (top or right) of the rectanglar shapes.
range	data ranges (the minimal and maximal values)
range_fixed	Whether the range is fixed for range when adjust the positions?

Details

This is an improved version of the smartAlign.

It adjusts the positions of the rectangular shapes to make them do not overlap

Examples

require(circlize)
make_plot = function(pos1, pos2, range) {
    oxpd = par("xpd")
    par(xpd = NA)
    plot(NULL, xlim = c(0, 4), ylim = range, ann = FALSE)
    col = rand_color(nrow(pos1), transparency = 0.5)
    rect(0.5, pos1[, 1], 1.5, pos1[, 2], col = col)
    rect(2.5, pos2[, 1], 3.5, pos2[, 2], col = col)
    segments(1.5, rowMeans(pos1), 2.5, rowMeans(pos2))
    par(xpd = oxpd)
}

range = c(0, 10)
pos1 = rbind(c(1, 2), c(5, 7))
make_plot(pos1, smartAlign2(pos1, range = range), range)

range = c(0, 10)
pos1 = rbind(c(-0.5, 2), c(5, 7))
make_plot(pos1, smartAlign2(pos1, range = range), range)

pos1 = rbind(c(-1, 2), c(3, 4), c(5, 6), c(7, 11))
pos1 = pos1 + runif(length(pos1), max = 0.3, min = -0.3)
omfrow = par("mfrow")
par(mfrow = c(3, 3))
for(i in 1:9) {
    ind = sample(4, 4)
    make_plot(pos1[ind, ], smartAlign2(pos1[ind, ], range = range), range)
}
par(mfrow = omfrow)

pos1 = rbind(c(3, 6), c(4, 7))
make_plot(pos1, smartAlign2(pos1, range = range), range)

pos1 = rbind(c(1, 8), c(3, 10))
make_plot(pos1, smartAlign2(pos1, range = range), range)
make_plot(pos1, smartAlign2(pos1, range = range, range_fixed = FALSE), range)
