google到很多资源，整理如下：
一.sas
HILOCTJ interpolation
1.1 proc gplot gchart等
a.support.sas官网的例子：带误差线的均值图
http://support.sas.com/kb/42/515.html
b.几篇文章
“A Generalized Procedure to Create SAS®/Graph Error Bar Plots”
“How To Plot A Line Chart With A Standard Error”
“How to Get Upper (or Lower) Error Bars with INTERPOL=HILOCTJ?”
1.2proc sgplot等sg语句
a.官网例子：带误差线的均值图
http://support.sas.com/kb/42/542.html
b.两个博客: bar charts
（sgplot）http://blogs.sas.com/content/iml/2011/10/07/creating-bar-charts-with-confidence-intervals/
(gchart and r)http://sas-and-r.blogspot.com/2011/11/example-915-bar-chart-with-error-bars.html
二、R
1.sas-and-r-blogspot博客中提到sciplot包
2.gplots包：plotCI函数
# plot means and
data(state)
tmp <- split(state.area, state.region)
means <- sapply(tmp, mean)
stdev <- sqrt(sapply(tmp, var))
n <- sapply(tmp,length)
ciw <- qt(0.975, n) * stdev / sqrt(n)
# plain
plotCI(x=means, uiw=ciw)
# prettier
plotCI(x=means, uiw=ciw, col="black", barcol="blue", lwd=1)
# give mean values
plotCI(x=means, uiw=ciw, col="black", barcol="blue",
labels=round(means,-3), xaxt="n", xlim=c(0,5) )
axis(side=1, at=1:4, labels=names(tmp), cex=0.7)
3.ggplot2包，
例：http://wiki.stdout.org/rcookbook/Graphs/Plotting%20means%20and%20error%20bars%20(ggplot2)/
