两个方法，一个都重现不了。。。。。。。。。

1、ForestPlot <- read_sav("C:\Users\user\Documents\Forest Plot.sav") attach(ForestPlot) forestplot(as.matrix(Forest_Plot[,1:3]), HR, LowerCI, UpperCI,             graph.pos=2,zero=1, graphwidth=unit(50,"mm"),             lineheight="auto", boxsize=0.1, xticks=(c(0.5,1.0,1.5,2.0,2.5)),             col= fpColors(all.elements = "black"))

Error in NCOL(mean) : object 'HR' not found

2、metan hr lowerci upperci, label(namevar=variables) fixed effect(HR) xlabel(0.5,1,1.5,2,2.5) force nowt nooverall nobox null(1) command metan is unrecognized r(199);
