if you do:
glimpse(head(iris))
you will see :
Rows: 6
Columns: 5
$ Sepal.Length <dbl> 5.1, 4.9, 4.7, 4.6, 5.0, 5.4
$ Sepal.Width <dbl> 3.5, 3.0, 3.2, 3.1, 3.6, 3.9
$ Petal.Length <dbl> 1.4, 1.4, 1.3, 1.5, 1.4, 1.7
$ Petal.Width <dbl> 0.2, 0.2, 0.2, 0.2, 0.2, 0.4
$ Species <fct> setosa, setosa, setosa, setosa, setosa, setosa
the <dbl> and <fct> type indicators in your console will be a different colour and italicised.
The encoding for the console to print them thatway looks like the sort of strange codes you shared.
Here is a method to roughly get the glimpse info in a plainer text.
for my money, glimpse is just a jazzed up version of str on data.frame for when the console supports that. So I would just use
str(head(iris))
'data.frame': 6 obs. of 5 variables:
$ Sepal.Length: num 5.1 4.9 4.7 4.6 5 5.4
$ Sepal.Width : num 3.5 3 3.2 3.1 3.6 3.9
$ Petal.Length: num 1.4 1.4 1.3 1.5 1.4 1.7
$ Petal.Width : num 0.2 0.2 0.2 0.2 0.2 0.4
$ Species : Factor w/ 3 levels "setosa","versicolor",..: 1 1 1 1 1 1
