的PNG/JPEG/SVG/TIFF/BMP設備
我只是想挽救一個情節到一個文件，它看起來像它沒有一個整體R系列設備：任何問題R中
getgrob = function(x, y) {
require(grid)
x = 1:10
y = rnorm(10)
plotvp = plotViewport(c(5, 5, 3, 3), name='plotvp')
datavp = dataViewport(x, y, name='datavp')
datapts = pointsGrob(
x, y, pch=20,
size=unit(2.3, 'mm'),
name='datapts',
gp=gpar(col='black')
)
xaxis = xaxisGrob()
yaxis = yaxisGrob()
xlab = textGrob('X Label', y=unit(-3, 'lines'), name='xlab')
ylab = textGrob('Y Label', x=unit(-3, 'lines'), rot=90, name='ylab')
plotbox = rectGrob()
dataplot = gTree(children=gList(datapts,
xaxis, yaxis,
xlab, ylab,
plotbox),
vp=datavp, name='dataplot')
wholeplot = gTree(children=gList(dataplot),
vp=plotvp, name='wholeplot')
wholeplot
}
pdf('/tmp/a.pdf')
mygrob = getgrob(1:10, rnorm(10))
grid.draw(mygrob)
dev.off()
png('/tmp/a.png')
mygrob = getgrob(1:10, rnorm(10))
grid.draw(mygrob)
dev.off()
jpeg('/tmp/a.jpg')
mygrob = getgrob(1:10, rnorm(10))
grid.draw(mygrob)
dev.off()
tiff('/tmp/a.tiff')
mygrob = getgrob(1:10, rnorm(10))
grid.draw(mygrob)
dev.off()
bmp('/tmp/a.bmp')
mygrob = getgrob(1:10, rnorm(10))
grid.draw(mygrob)
dev.off()
svg('/tmp/a.svg')
mygrob = getgrob(1:10, rnorm(10))
grid.draw(mygrob)
dev.off()
我得到的是一個空白區域與軸和扁蝨：
但PDF設備仍然有效。我在這裏錯過了什麼嗎？
