Compare the dotplot to a histogram of the data. (Select all that apply.)
a：Dotplots show the frequency of individual data values.
b：The raw data can be retrieved from the dotplot, but not the histogram.
c：The dotplot and histogram both show a greater density from 280 to 340.
d：Histograms show the frequency of individual data values.
E：The raw data can be retrieved from the histogram, but not the dotplot

发帖数: 587 | 4 俺是这样的：
xyplot(x~y, jitter.x=T, col=c("red", "green"), xlim=c("1", "2"))
boxplot(x~y, add=T)
问题是两个图是在一起， 但是轴，x, y, 不完全吻合， 只能说勉强可用。
试过把boxplot 放在panel里， 同样不行， 还比不上用 add=T
google did not give me a good solution either, there seems to have a
gplots package, but that seems to work only on linux
谢谢 |

发帖数: 587 | 6 Thanks.
seems it worked like this:
library(lattice)
bwplot(x~factor(y), data=X,
panel = function(x,y) {
panel.xyplot(x,y, pch=, jitter.x=T, factor=1.5)
panel.bwplot(x,y, horizontal=F, notch=T, fill=c("green", "
red"))
}
)
The issues now are:
1. fill is not transparent, so the dots in box region are covered.
2. I am not sure about the xyplot's col, when I give it col=c("red", "green"
),
it seems to color dots randomly, instead of based on groups in |
