interaction.plot {stats} R Documentation
Two-way Interaction Plot
Description
Plots the mean (or other summary) of the response for two-way combinations of factors, thereby illustrating possible interactions.
Usage
interaction.plot(x.factor, trace.factor, response, fun = mean,
type = c("l", "p", "b", "o", "c"), legend = TRUE,
trace.label = deparse1(substitute(trace.factor)),
fixed = FALSE,
xlab = deparse1(substitute(x.factor)),
ylab = ylabel,
ylim = range(cells, na.rm = TRUE),
lty = nc:1, col = 1, pch = c(1:9, 0, letters),
xpd = NULL, leg.bg = par("bg"), leg.bty = "n",
xtick = FALSE, xaxt = par("xaxt"), axes = TRUE,
...)
使い方
- モデル式ではなく、もとのデータフレームから、計算して図を描く
基本はこの三つ
- x.factor=データ$横軸に並べる要因
- trace.factor=データ$図を描く要因
- response=データ$縦軸に並べる応答変数
interaction.plot(x.factor=both13.dat$year, trace.factor=both13.dat$mode, response=both13.dat$IPSyn13)
