I have executed a research to assess the performance among diagnostics kits. I could determine the statistical components except Cohen's kappa coefficient. Here I compiled my data in binary values [1=positive, 0=negative]. To check the agreements among data I am in a need of calculating kappa coefficient. If anyone could provide me with syntax to calculate kappa coefficient using either Python or R I would be much obliged and feel grateful.

Try https://www.statsmodels.org/stable/generated/statsmodels.stats.inter_rater.cohens_kappa.html
Revelle's psych package can compute kappa coefficient (https://www.rdocumentation.org/packages/psych/versions/2.1.9/topics/cohen.kappa) You can learn more about his package at http://personality-project.org/revelle.html

Hi I think you this link will help you https://scikit-learn.org/stable/modules/generated/sklearn.metrics.cohen_kappa_score.html
I also strongly recommended you to read this paper:
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0222916
The authors made an interesting discussion about this coefficient to validate a classification problem.
All the best
