Possible to print more than 100 rows of a data.table?
The print method of data.table has an argument nrows:
args(data.table:::print.data.table)function (x, nrows = 100L, digits = NULL, ...) You can use this to control how many rows get printed:
print(dtIris, nrow=105).....99: 5.1 2.5 3.0 1.1 versicolor100: 5.7 2.8 4.1 1.3 versicolor101: 6.3 3.3 6.0 2.5 virginica102: 5.8 2.7 5.1 1.9 virginica103: 7.1 3.0 5.9 2.1 virginica104: 6.3 2.9 5.6 1.8 virginica105: 6.5 3.0 5.8 2.2 virginica Sepal.Length Sepal.Width Petal.Length Petal.Width Species
View() (as in View(iris) or View(dtIris[1:120,])) doesn't truncate data.tables, and can often be nicer than printing/spewing out a data.* to the console.
To print the top 60 and bottom 60 lines (default is top 5 and bottom 5):
print(dtIris, topn = 60)
