Rstudio进行网状meta遇到的报错

求助，使用Rstudio进行计数资料分析时，导入数据后输入下面的代码报错

network < - mtc.network(thrombosis, description="thrombosis network", treatments = treatments)

summary(network)

报错： network < - mtc.network(thrombosis, description="thrombosis network", treatments = treatments)

Error: object 'network' not found

> summary(network)

Error in summary(network) : object 'network' not found

请大神们指教
