根据向量名识别并绑定多个向量

I have 100 numeric vectors named sim1 to sim100 in my workspace, all of the same length (18). I'm trying to find a way to identify them and cbind them to create a data frame of 18 rows and 100 columns. I can easily create a character vector of length 100 that contains the names of the vectors:I have 100 numeric vectors named sim1 to sim100
