我想将行为空的列中的值替换为我的列tech.role的“NO”

mental.health$tech.role <- as.factor(mental.health$tech.role)
levels(mental.health$tech.role)<-c("No","Yes")
Error in `levels<-.factor`(`*tmp*`, value = c("No", "Yes")) : 
  number of levels differs

mental.health$tech.role
mental.health$tech.role[is.na（mental.health$tech.role）]请使用
dput
功能将
mental.health
数据框添加到问题中（强调最小值）。这将帮助我们找出问题所在，并为您提供有用的答案

mental.health$tech.role[is.na(mental.health$tech.role)] <- 'NO'
