發(fā)現(xiàn)R圖的線條粘到Word文檔之后很模糊，請(qǐng)問(wèn)如何設(shè)置R圖線條的粗細(xì)？

plot里面用lwd，將取合適的值然后放在作圖的函數(shù)里，實(shí)際上我們可以查看繪圖函數(shù)幫助文檔：

plot {graphics} R Documentation

Generic X-Y Plotting

Description

Generic function for plotting of R objects. For more details about the graphical parameter arguments, see par.

For simple scatter plots, plot.default will be used. However, there are plot methods for many R objects, including functions, data.frames, density objects, etc. Use methods(plot) and the documentation for these.

Usage

plot(x, y, ...)

Arguments

x

the coordinates of points in the plot. Alternatively, a single plotting structure, function or any R object with a plot method can be provided.

y

the y coordinates of points in the plot, optional if x is an appropriate structure.

...

Arguments to be passed to methods, such as graphical parameters (see par). Many methods will accept the following arguments:

type

what type of plot should be drawn. Possible types are

"p" for points,

"l" for lines,

"b" for both,

"c" for the lines part alone of "b",

"o" for both ‘overplotted’,

"h" for ‘histogram’ like (or ‘high-density’) vertical lines,

"s" for stair steps,

"S" for other steps, see ‘Details’ below,

"n" for no plotting.

All other types give a warning or an error; using, e.g., type = "punkte" being equivalent to type = "p" for S compatibility. Note that some methods, e.g. plot.factor, do not accept this.

main

an overall title for the plot: see title.

sub

a sub title for the plot: see title.

xlab

a title for the x axis: see title.

ylab

a title for the y axis: see title.

asp

the y/x aspect ratio, see plot.window.

Examples

require(stats) # for lowess, rpois, rnorm

plot(cars)

lines(lowess(cars))

plot(sin, -pi, 2*pi) # see ?plot.function

## Discrete Distribution Plot:

plot(table(rpois(100, 5)), type = "h", col = "red", lwd = 10,

main = "rpois(100, lambda = 5)")

## Simple quantiles/ECDF, see ecdf() {library(stats)} for a better one:

plot(x <- sort(rnorm(47)), type = "s", main = "plot(x, type = \"s\")")

points(x, cex = .5, col = "dark red")
