I want to extract some information from str output of a dataframe.
Tried this ...
> tmp <- str(iris) > tmp NULL Is it possible to store this in a variable?

str() function in R Language is used for compactly displaying the internal structure of a R object. It can display even the internal structure of large lists which are nested.
The str() function returns information about the rows(observations) and columns(variables) along with extra information like the names of the columns, class of each column, followed by some of the initial observations of each of the columns.
str does not stand for string, it stands for structure: str(…) displays the internal structure of a given R object.
You can use capture.output:
l = capture.output(str(mtcars)) l [1] "'data.frame':\t32 obs. of 11 variables:" [2] " $ mpg : num 21 21 22.8 21.4 18.7 18.1 14.3 24.4 22.8 19.2 ..." [3] " $ cyl : num 6 6 4 6 8 6 8 4 4 6 ..." [4] " $ disp: num 160 160 108 258 360 ..." [5] " $ hp : num 110 110 93 110 175 105 245 62 95 123 ..." [6] " $ drat: num 3.9 3.9 3.85 3.08 3.15 2.76 3.21 3.69 3.92 3.92 ..." [7] " $ wt : num 2.62 2.88 2.32 3.21 3.44 ..." [8] " $ qsec: num 16.5 17 18.6 19.4 17 ..." [9] " $ vs : num 0 0 1 1 0 1 0 1 1 1 ..." [10] " $ am : num 1 1 1 0 0 0 0 0 0 0 ..." [11] " $ gear: num 4 4 4 3 3 3 3 4 4 4 ..." [12] " $ carb: num 4 4 1 1 2 1 4 2 2 4 ..." If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
