[R] list of data frame objects

Hi Folks, I need to extract the list of all my data frame objects. With objects() I can list all objects and was hoping to use something like the following: objects()[is.data.frame(objects())] to extracts all my objects that are data frame... What am I doing wrong? Thanks - Tim

Re: [R] list of data frame objects

try something like the following (untested): objs - ls() sapply(objs, function(obj) inherits(get(obj), data.frame)) I hope it helps. Best, Dimitris Dimitris Rizopoulos Ph.D. Student Biostatistical Centre School of Public Health Catholic University of Leuven Address: Kapucijnenvoer 35,
