问题：

x5 <- factor(10)                               
# Create factor object

#
sqrt(x5)                                       
# Apply sqrt to factor

解决：

#正确的玩法
x5_sqrt <- sqrt(as.numeric(as.character(x5)))  
# as.numeric, as.character & sqrt
x5_sqrt                                        
# Return output to RStudio console
