r - Issue with subsetting data; not picking up observations for one category -

-

i'm attempting subset data in r 1 column of spreadsheet 3 different categories: cod, haddock , whiting. reason however, haddock not working , saying there no observations subset, when in fact there should 51 - other 2 categories subsetting fine observations accounted for. can reasons this? spreadsheet appears ok, , doesn't seem contain obvious problems, there overlooking?

thanks

edit:

ok, here's part of data set here...

opcode                 species      distancefromcoast sa_f1_280714_c4_1   atlantic cod    583.69 sa_f1_280714_c4_1   haddock         583.69 sa_f1_280714_c4_1   whiting         583.69 sa_f1_290714_c2_10  atlantic cod    892.51 sa_f1_290714_c2_10  haddock         892.51 sa_f1_290714_c2_10  whiting         892.51 sa_f1_280714_c4_6   haddock         1080.5 sa_f1_280714_c4_6   whiting         1080.5 sa_f1_280714_c4_6   atlantic cod    1080.5 sa_f1_280714_c4_7   whiting         1030.59 sa_f1_280714_c4_7   haddock         1030.59 sa_f1_280714_c4_7   atlantic cod    1030.59

maybe there class of variables. try

str(dat) 'data.frame':   12 obs. of  3 variables:  $ opcode           : factor w/ 4 levels "sa_f1_280714_c4_1",..: 1 1 1 4 4 4 2 2 2 3 ...  $ species          : factor w/ 3 levels "atlantic cod",..: 1 2 3 1 2 3 2 3 1 3 ...  $ distancefromcoast: num  584 584 584 893 893 ...

a grouping operation should work fine,

library(dplyr) dat %>% group_by(species) %>%   summarise(ave.dist = mean(distancefromcoast)) #        species ave.dist # 1 atlantic cod 896.8225 # 2      haddock 896.8225 # 3      whiting 896.8225

to graph group using ggplot2, need specify grouping option in aes (ie. color, shape, group, etc).

library(ggplot2) ggplot(dat, aes(x=species, y=distancefromcoast, fill=species)) + geom_bar(stat="identity")

PHP DOM loadHTML() method unusual warning -

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null

python - How to create jsonb index using GIN on SQLAlchemy? -

here's current code creating index jsonb. index("mytable_data_idx_id_key", mytable.data['id'].astext, postgresql_using='gin') but got error. sqlalchemy.exc.programmingerror: (psycopg2.programmingerror) data type text has no default operator class access method "gin" hint: must specify operator class index or define default operator class data type.

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
