How to plot family tree in R -

-

i've been searching around how plot family tree couldn't find reproduce. i've been looking in hadley's book ggplot same thing.

i want plot family tree having source dataframe similar this:

dput(head(familytree)) structure(   list(     id = 1:6,      cnp = c("11", na, "22", na, na, "33"),      last_name = c("b", "b", "b", na, na, "m"),      last_name_alyas = c(na, na, na, na, na, "m"),      middle_name = c("c", na, na, na, na, na),      first_name = c("me", "p", "a", na, na, "s"),      first_name_alyas = c(na, na, na, na, na, "f"),      maiden_name = c(na, na, "m", na, na, na),      id_father = c(2l, 4l, 6l, na, na, 8l),      id_mother = c(3l, 5l, 7l, na, na, 9l),      birth_date = c("1986-01-01", "1963-01-01", "1964-01-01", na, na, "1936-01-01"),      birth_place = c("city", "village", "village", na, na, "village"),      death_date = c("0000-00-00", na, na, na, na, "2007-12-23"),      death_reason = c(na, na, na, na, na, "stroke"),      nr_brothers = c(na, 1l, na, na, na, na),  brothers_names = c(na, "m", na, na, na, na),      nr_sisters = c(1l, na, 1l, na, na, 2l),      sisters_names = c("a", na, "e", na, na, na),      school = c(na, "", "", na, na, ""),      occupation = c(na, "", "", na, na, ""),      diseases = c(na_character_, na_character_, na_character_, na_character_, na_character_, na_character_),      comments = c(na_character_, na_character_, na_character_, na_character_, na_character_, na_character_)   ),    .names = c("id", "cnp", "last_name", "last_name_alyas", "middle_name", "first_name", "first_name_alyas", "maiden_name", "id_father", "id_mother", "birth_date", "birth_place", "death_date", "death_reason", "nr_brothers", "brothers_names", "nr_sisters", "sisters_names", "school", "occupation", "diseases", "comments"),    row.names = c(na, 6l),    class = "data.frame" )

is there way can plot family tree ggplot? if not, how can plot using package.

the primary key 'id' , connect other members of family using "id_father" , "id_mother".

as noted in comments, should try igraph. here quick start:

require(igraph) mothers=familytree[,c('id','id_mother','first_name', 'last_name')] fathers=familytree[,c('id','id_father','first_name', 'last_name')] mothers$name=paste(mothers$first_name,mothers$last_name) fathers$name=paste(fathers$first_name,fathers$last_name) names(mothers)=c('parent','id','first_name','last_name','name') names(fathers)=c('parent','id','first_name','last_name','name') links=rbind(mothers,fathers) links=links[!is.na(links$id),] g=graph.data.frame(links) co=layout.reingold.tilford(g, flip.y=f) plot(g,layout=co)

enter image description here

there aren't names, , arrows going in wrong direction, should able go there.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
