I'm wondering about the word "dataset". It seems to be in pretty common usage in technical writing these days, compared to "data set", which dictionary.com tells me originated in the early '70s. MS Word's spell checker catches "dataset", but since both data and set are bound to be in its dictionary, I'm not sure that "dataset" is wrong so much as just not in the dictionary.
Is the usage of "dataset" common enough that it's acceptable? Or should I stick with "data set"?
