Rstudio使用过程中出现问题

data: rate$p
W = 0.4973, p-value = 5.942e-06

meta1 <- metaprop(Case,Sample.size,data=data,studlab = paste(data$Author,data$Year,sep="-"),sm="PRAW",incr=0.5,allincr=TRUE,addincr=FALSE)
Error in metaprop(Case, Sample.size, data = data, studlab = paste(data$Author, :
Number of events must not be larger than number of observations

在学习过程中一直报错，请求指点，用教程中的模板数据就一点问题都没有。
