R dataset with $ NULL:'data.frame'? -

it may dummy questions i'm stuck here.

i have next dataset in r:

> str(he) list of 1 $ null:'data.frame': 29 obs. of 10 variables: ..$ date : factor w/ 4 levels "","october 15, 2014 4:13 pm",..: 3 1 1 1 1 3 1 1 1 3 ... ..$ receipt : factor w/ 14 levels "","-1 discount",..: 14 3 7 5 2 13 4 8 6 12 ... ..$ register: factor w/ 11 levels "-300.00","-400.00",..: 11 7 4 4 1 11 5 4 4 11 ... ..$ user : factor w/ 4 levels "","cash","credit card",..: 4 1 1 1 1 4 3 1 1 4 ... ..$ customer: factor w/ 4 levels "","1,000.00",..: 1 na na na na 1 2 na na 1 ... ..$ notes : factor w/ 1 level "": 1 na na na na 1 na na na 1 ... ..$ products: factor w/ 1 level "total sale": 1 na na na na 1 na na na 1 ... ..$ total : factor w/ 3 levels "0.00","1,000.00",..: 1 na na na na 2 na na na 3 ... ..$ payments: factor w/ 1 level "total paid": 1 na na na na 1 na na na 1 ... ..$ paid : factor w/ 3 levels "0.00","1,000.00",..: 1 na na na na 2 na na na 3 ...

however, don't seem able access data. instance:

> he$date null

there $ null:'data.frame'. can help? thanks.

your str(he) output says all. list of 1... means data.frame residing within list. best thing either re-assign 'he' data.frame, or create new data.frame reference elements within it. e.g

df_he <- he[[1]] df_he$date
