How to get number of occurrences in R for Naive Bayes Classification -

-

i pretty new r , trying analyse example dataset started naive bayes classification. 

day     outlook  temperature    humidity    wind    play 1       sunny    hot            high        weak    no   2       sunny    hot            high        strong  no   3       overcast hot            high        weak    yes   4       rain     mild           high        weak    yes   5       rain     cool           normal      weak    yes   6       rain     cool           normal      strong  no   7       overcast cool           normal      strong  yes   8       sunny    mild           high        weak    no   9       sunny    cool           normal      weak    yes   10      rain     mild           normal      weak    yes   11      sunny    mild           normal      strong  yes   12      overcast mild           high        strong  yes   13      overcast hot            normal      weak    yes   14      rain     mild           high        strong  no

i have been able use table() function number of occurrences of each value categorical variables outlook, temperature, humidity, wind , play. proceed next stage need calculate corresponding number of occurrences of each value of categorical variables particular target class value of yes , no. example know number of occurrences of x(outlook=sunny,play=no) 2 above dataset, command should use desired result?

note: know naive bayes 1 calculates probability more interested in getting frequency in case.

are looking this:

by(df[-1], df$play, sapply, table)

? (assuming df dataframe.)

result:

df$play: no $outlook  overcast     rain    sunny         0        2        3   $temperature  cool  hot mild     1    2    2   $humidity    high normal       4      1   $wind  strong   weak       3      2   $play   no yes    5   0   -----------------------------------------------------------------------------------------------------------------------------  df$play: yes $outlook  overcast     rain    sunny         4        3        2   $temperature  cool  hot mild     3    2    4   $humidity    high normal       3      6   $wind  strong   weak       3      6   $play   no yes    0   9

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
