r - how to graph using geom_area? -
does know why data not graphing? data_frame univ_apps ---------------------------- timeappreceived chr may_12_2002, march_4_2002 bs_ms_phd factor 1 bs 2 ms 3 phd appid int rn89 qw23 et43 sample data -------------- timeappreceived bs_ms_phd appid sept_2_1989 1 rn89 sept_2_1989 2 dq11 oct_1_2011 1 bg32 etc univdata = ggplot(univ_apps, aes(x= yearappreceived, y= appid, fill=as.factor(bs_ms_phd))) + geom_area(position="stack") am missing command graph? the data frame shown, "timeappreceived" chr. guess data type of "yearappreceived" same "timeappreceived". should convert numeric. try following code. univdata = ggplot(univ_apps, aes(x= as.integer(yearappreceived), y= appid, fill=as.factor(bs_ms_phd))) + geom_area(position="stack"); univdata by way, if appid not numeric, shoud convert them too. appid integer, isn't it?
