headtail {psych} | R Documentation |
A quick way to show the first and last n lines of a data.frame, matrix, or a text object. Just a pretty call to head
and tail
headtail(x,hlength=4,tlength=4,digits=2)
x |
A matrix or data frame or free text |
hlength |
The number of lines at the beginning to show |
tlength |
The number of lines at the end to show |
digits |
Round off the data to digits |
The first hlength and last tlength lines of a matrix or data frame with an ellipsis in between. If the input is neither a matrix nor data frame, the output will be the first hlength and last tlength lines.
x <- matrix(sample(10,1000,TRUE),ncol=5) headtail(x,4,8)
