R语言—图形基础
将数据变成图表，进行数据分析，文字少，分析结果简洁明了，能够提高人们的视觉效应，能更快读取原始数据，合理的使用图表，能够提升人们对数据的理解能力，节约阅览的时间。本节细致归纳了绘制图形并保存中涉及的基本参数以及实例。
| bmp() | bmp(filename = “Rplot%03d.bmp”,width = 480, height = 480,units = “px”, pointsize = 12,bg = “white”,res =NA, family ="",restoreConsole = TRUE,type = c(“windows”, “cairo”), antialias,symbolfamily=“default”) |
| png() | png(filename = “Rplot%03d.png”,width = 480, height = 480, units = “px”, pointsize = 12,bg = “white”, res = NA, family = “”, restoreConsole = TRUE,type = c(“windows”, “cairo”, “cairo-png”), antialias,symbolfamily=“default”) |
| jpeg() | jpeg(filename = “Rplot%03d.jpg”,width = 480, height = 480, units = “px”, pointsize = 12,quality = 75,bg = “white”, res = NA, family = “”, restoreConsole = TRUE,type = c(“windows”, “cairo”), antialias,symbolfamily=“default”) |
| tiff() | tiff(filename=“Rplot%03d.tif”,width=480,height=480,units=“px”,pointsize=12,compression=c(“none”, “rle”, “lzw”, “jpeg”, “zip”, “lzw+p”, “zip+p”),bg = “white”, res = NA,family = “”,restoreConsole = TRUE,type = c(“windows”, “cairo”), antialias,symbolfamily=“default”) |
| pdf() | pdf(file = if(onefile) “Rplots.pdf” else “Rplot%03d.pdf”,width, height, onefile, family, title, fonts, version,paper, encoding, bg, fg, pointsize, pagecentre, colormodel,useDingbats, useKerning, fillOddEven, compress) |
| win.metafile() | win.metafile(filename = “”, width = 7, height = 7, pointsize = 12,family,restoreConsole = TRUE) |
| xfig() | xfig(file = if(onefile) “Rplots.fig” else “Rplot%03d.fig”,onefile = FALSE, encoding = “none”,paper = “default”, horizontal = TRUE,width = 0, height = 0, family = “Helvetica”,pointsize = 12, bg = “transparent”, fg = “black”,pagecentre = TRUE, defaultfont = FALSE, textspecial = FALSE) |
| postscript() | postscript(file = if(onefile) “Rplots.ps” else “Rplot%03d.ps”,onefile, family, title, fonts, encoding, bg, fg,width, height, horizontal, pointsize,paper, pagecentre, print.it, command,colormodel, useKerning, fillOddEven) |
除此之外，还可以通过dev.new()函数打开一个新的图形窗口，在窗口内点击【文件】→【另存为】，选择合适的文件格式保存图形内容。
