r - Using rbind.fill does not fill the correct value -

-

i don’t understand how rbind.fill works, guess. have data frame called main.df:

     tlt pcy shy vti tip vnq vwo rwx vea dbc gld pct   0   0   0   0   0   0   0   0   0   0   0

i want bind following different-sized data frame named p.df it:

          vwo       vea       vti pct 0.3333333 0.3333333 0.3333333

when execute rbind.fill(main.df, p.df) get:

  tlt pcy shy vti tip vnq vwo rwx vea dbc gld 1   0   0   0   0   0   0   0   0   0   0   0 2  na  na  na   1  na  na   1  na   1  na  na

which not want. expected get:

  tlt pcy shy vti     tip vnq  vwo     rwx vea    dbc gld 1   0   0   0   0       0   0    0       0   0     0   0  2  na  na  na   0.333   na  na   0.333  na  0.333  na  na

how do this? dput of objects below.

main.df <- structure(list(   tlt = 0, pcy = 0, shy = 0, vti = 0, tip = 0, vnq = 0, vwo = 0, rwx = 0, vea = 0, dbc = 0, gld = 0),   .names = c("tlt", "pcy", "shy", "vti", "tip", "vnq", "vwo", "rwx", "vea", "dbc", "gld"),   row.names = "pct", class = "data.frame")  p.df <- structure(list(   vwo = structure(1l, .names = "pct", .label = c("0.3333333", "vwo"), class = "factor"),   vea = structure(1l, .names = "pct", .label = c("0.3333333", "vea"), class = "factor"),   vti = structure(1l, .names = "pct", .label = c("0.3333333", "vti"), class = "factor")),   .names = c("vwo", "vea", "vti"), row.names = "pct", class = "data.frame")

it if provided reproducible example using dput(main.df) , dput(p.df), appears 1 or both of objects contain factor vectors, not numeric vectors. need convert them.

main.df[] <- lapply(main.df, function(f) as.numeric(levels(f))[f]) p.df[] <- lapply(p.df, function(f) as.numeric(levels(f))[f])

see how convert factor integer\numeric without loss of information details.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
