i trying left-outer-join on 2 tables using linq using this answer. when try add fields contactsrow object array argument of .loaddatarow() function, editor says 'contactsrow' not exist in current context. how code different answer in link? have been trying learn lineq avoid crazy-nested loops has me stumped. more code here.

edit:

var joinedtables =  tablerow in filteredtable.asenumerable()                             join contactsrow in contacts.asenumerable()                             on tablerow.field<double>("opportunity: store number") equals contactsrow.field<double>("national store .")                             lj                             r in lj.defaultifempty()                             select resulttable.loaddatarow(new object[]                             {                                 tablerow.field<double>("opportunity: store number"),                                 tablerow.field<datetime>("target circuit completion (foc)"),                                 tablerow.field<string>("vendor name"),                                 r.field<string>("contacts - acm - email"),                                 r.field<string>("oo - ops mgr name"),                                 r.field<string>("contacts - area sup / bc - email"),                                 r.field<string>("contacts - otp - email"),                                 r.field<string>("otm email address")                             }, false);         return resulttable;

i changed code resulttable r in select statement suggested. code compiles resulttable empty.

you need select r not contactsrow.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
