tense is tricky

[softloud]

As a native english speaker, I struggle with tense, so take my suggestions with a grain of salt. However, I think this would flow better

The application widespread of economic complexity shall be looked with a bit of caution.

if this was

The application widespread of economic complexity should be considered with caution.

And :woman_facepalming: "grain of salt" is a native-english idiom. I mean to say, feel free to disregard my suggestions.

In a previous life, I worked as a copywriter for advertising, so I can be needlessly picky about grammar.

fwiw, I think this reads very well. It does read as non-native English. But the quality of the writing is sufficient that the native speaker can accommodate.

That being said, I shall continue with comments that can be happily disregarded.

Economic complexity is a state-of-the-art line of research that started back nearly ten years ago and introduces network theory concepts to study different social sciences issues related to international trade and income inequality.

I'd rephrase "started back nearly ten years ago"; it reads as informal to a native.

Consider replacing with something along the lines of

Economic complexity introduces network theory concepts to different social science [use singular] considerations related to international trade and income inequality. With the bulk of literature established in the last decade, the field of economic complexity is relatively new.

Seminal papers in economic complexity are @productspace2007, that introduces graphs to explore trade diversification and export opportunities, and @buildingblocks2009, that develops dedicated metrics of complexity.

Replace 'that' with 'which'

Seminal papers in economic complexity are: @productspace2007, which introduces graphs to explore trade diversification and export opportunities; and @buildingblocks2009, which develops dedicated metrics of complexity.

economiccomplexity might help to evaluate research findings in this particular area, helping to produce less studies that are not reproducible, or partially reproducible with some discrepancies, conditional on the availability of data, metadata, and computing power that may be unavailable to all researchers.

The central contribution of this package is to be the first that provides functions to use the recursive linear algebra methods from @buildingblocks2009 in R and adds tests and full documentation to offer the best possible package on CRAN.

to be the first can be encapsulated with the 'central contribution'

The central contribution of economiccomplexity:: is to provide functions that use recursive linear algebra methods from @buildingblocks2009 in R, with tests and full documentation for release on CRAN, the dominant repository of R software.

thanks a lot !!
