问题 I am encountering an issue when using dplyr in a function. When filtering based on a quosure, the > sign appears to cause an issue where no data are returned. For example: temp_df <- data.frame( startdate_c = as.Date(c("2011-08-08", "2007-09-01", "2012-01-01", "2012-10-26", "2012-12-01", "2016-01-01", "2006-06-01", "2009-04-01", "2005-02-09", "2004-08-01")), enddate_c = as.Date(c("2011-08-14", "2012-09-04", "2014-06-06", "2014-02-28", "2013-04-05", "2016-12-01", "2008-04-18", "2009-08-16",
