从 R 中的数组中提取辅助日期

Question

I have an object called data (representing a field of wind strengths at geographical locations) obtained by using some code to read in a.grib file:

> data
ecmf : u-component of wind  
Time:
2020/07/09 z00:00 0-0 h 
Domain summary:
601 x 351 domain
Projection summary:
proj= latlong 
NE = ( 50 , 75 )
SW = ( -10 , 40 )
Data summary:
-89.06099 -50.08242 -41.13694 -43.42623 -34.77617 -25.03278 

data is 601 x 351 array of doubles:

> typeof(data)
[1] "double"
> is.array(data)
[1] TRUE
> dim(data)
[1] 601 351

but, as shown above, it also has extra information attached beyond the numerical values of the array elements ( Time: , Projection summary etc). How do I extract these? Attempts such as data$time do not seem to work.

Answer 1

As suggested in the comments to the question, I was able to access the values I wanted using attributes() . attributes(data) returns a list of all the relevant elements.
