i'm new r. run analysis in sas. however, need use fastica in r. i've conducted independent component analysis in r , looking extract actual components. the code i've used follows: ica<-fastica(final_all_truncated_s, n.comp = 100) ica list 5 elements "x" "k" "w" "a" "s" i extract values these elements, save excel file, , import sas. question is, how extract values these elements can export excel file? rather saving results excel format, recommend saving each component of result separate csv file. this way don't need additional packages, , have software-independent file format can read sas, excel, etc. you can achieve using simple for-loop in r, e.g.: for (x in names(ica)) { write.csv(ica[[x]], file=sprintf('%s.csv', x), row.names=false, quote=false) } here, names(ica) returns vector of list indices ("x", "k", "w", "a", , "s")...

i working on 2.5d lighting problem. wanted create effect moon lighting 2d things behind. have ever seen solution problem this? i'm trying use normal maps on sprite in unity, looks fine-ish when moon poking out behind -- when it's behind (as in third picture), effect doesn't work -- because light 2d element in 3d, have light front, far know perhaps there's solution doesn't involve real light, shaders reveal angle-based mask. have bright (haw!) ideas? i'm not familiar using 2d objects i'm guess going have simulate effect using transparency , looking function calculate brightness origin (the center of moon) or (not sure if possible) maybe create 3d overlay (or backlay if will) uses material give desired look.....set transparency on 2d object allow light effects of 3d rectangle shine though.. there beter solutions, i'm throwing ideas around

i started cv course , going through old homeworks (the current ones aren't released). i've implemented hough lines function, loop through each point, if it's edge, loop through 0-180 (or -90 90) theta values, , calculate rho, , store in array. when tried convert polar coordinates, can find x,y pair (using rho * sin(theta), , rho * cos(theta)), don't understand how convert line in cartesian space. have line need either 2 points or point , direction (assuming ray of course) i understand point is. i've done searching can't seem quite find answer, folks tend say, polar tells x, bam have line in cartesian, seem missing connection "bam" was. what mean described here; explain hough transformation also vector/line polar coordinates it's asked how draw line polar coords, response here's x , y. me never mentions rest of solution. is line somehow related y = mx+b m theta , b rho? if not how convert line in cartesian space. edit: afte...

looking view can list 'invalid' objects in postgresql. in oracle, can use dab_objects.status column i'm not sure if there simple way such thing in postgresql. maybe, can check invalid indexes below code. how can other objects? select pg_class.relname pg_class, pg_index pg_index.indisvalid = false , pg_index.indexrelid = pg_class.oid; i don't think have check else, since other objects cannot become invalid in postgresql. oracle , postgresql work quite differently in respect. in oracle, can alter object (for example table) if there dependent objects (for example views). dependent objects become invalid , have recompiled . in postgresql, cannot alter object has dependend objects in way renders these dependent objects invalid. have drop , recreate dependent objects. invalid indexes can left behind failed create index command.
