contact_matrix(counts = TRUE)$matrix is now an array rather than an xtabs object. This matches the existing output format of contact_matrix(counts = FALSE)$matrix (#118).limits_to_agegroups has been changed to return bracket notated age ranges by defaultAn error in list_surveys() was fixed which stopped this working.
contact_matrix() was updated to only accept survey objects, not DOIs and matches the documentation. It is still possible to get a contact matrix from a DOI but it is necessary to go through the get_survey() function.

contact_matrix()
The efficiency of the contact_matrix() was improved.
cite function has been deprecated and replaced with get_citation (#84).columns argument has been removed from check.survey() (#81).download_survey() has been reduced by externalising the find_common_prefix() function and failing early instead of relying on unnecessary if/else sequenceserror argument has been removed from check() and always return warnings. If you want to turn these warnings into errors, please have a look at options(warn = 2)quiet argument has been removed from check(), cite(), contact_matrix(), and get_survey(). If you want to silence diagnostic messages, you should use R idiomatic mechanisms, such as suppressMessages()n and bootstrap options of contact_matrix() have been deprecated and replaced with a sample.participants argument; bootstrapping is now explained in the vignette insteadmatrix_plot() function to plot contact matrixchkDots() is now used to ensure no argument is silently ignored by S3 methodsget_survey() has been split into separate functions for downloading and processing survey datareduce_agegroups
