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?
