QUESTION
I offered to help a friend with a problem, and am quickly realizing it is beyond my skills. I am interested in filtering to delete records of a group which fall on or after the first record of another group.
I am grouping by 'species', 'year', and 'sex', and would like to remove any records where 'sex' is "f" which occur after the first 'observation_doy' of the "m". In this example, the records I would like to delete are indicated in bold.

QUESTION
I have a dataset with oppurtunistic species-observations per square kilometer per year (ranging from 1900 to 2019).
There are 139 different sites (square kilomters) in my dataset. I want to make a dataset where for each species for every year for every site, its presence or absence is stated with 1 or 0.
I think this is the appropriate format for including the length of the species-list per year per site in a GLM, to try and account for repeated visits to sites within years (See Szabo et al. 2010 sci-hub.tw/10.1890/09-0877.1 for application of this method).
Data now looks like:

I need to transform a list of strings similar to this:
...ANSWER
Answered 2019-Jul-16 at 00:15Assuming that the values don't contain any whitespace (otherwise it would be hard to distinguish what part belongs to the previous value or to the next key), and stripping off the beginning of the string (not sure how the {'RECORD': '0'}
fits in the picture), you can use re.findall
with the following regex:

QUESTION
I have a list of bacteria each with it's own abundance in a dataframe. I also have the same list of bacteria but in a different order in the same dataframe.
I want to match the abundances to this second list but I'm not sure how to go about doing it.
dyplyr contains several methods for sorting data but I don't know how to match the abundance and print it into a new column so it now matches with the second list of bacteria.
Here's the beginning of my dataset:
...ANSWER
Answered 2018-Feb-21 at 12:16As others have mentioned, it's hard to test without some data that matches, but something like this should work, using match
to match up values.
