printing ff objects and compactly showing their structure
## S3 method for class 'ff' print(x, ...) ## S3 method for class 'ff_vector' print(x, maxlength = 16, ...) ## S3 method for class 'ff_matrix' print(x, maxdim = c(16, 16), ...) ## S3 method for class 'ff' str(object, nest.lev=0, ...) ## S3 method for class 'ffdf' str(object, nest.lev=0, ...)
x |

maxdim |
