I have a list of data.frames > str(bins)
List of 19217 $ 100026:'data.frame': 1 obs. of 6 variables: ..$ Sku : chr "100026" ..$ Bin : chr "T149C" ..$ Count: int 108 ..$ X : int 20 ..$ Y : int 149 ..$ Z : chr "3" $ 100030:'data.frame': 1 obs. of 6 variables: ....... As you can see one 'column' is "Count". This list seems to contain 19217 data.frames. I would like to create an array of 19217 integers which hold the values of the "Count" column. I have tried the obvious (to me): bins[[1:3]]$Count But that returns NULL instead of an array of length 3 that I was expecting. Interestingly bins[[1]]$Count returns the first "Count" in the list of data frames. How do I get all of the "Count"s? Thank you.
