r - Is there anything wrong with using T & F instead of TRUE & FALSE? -


i noticed using t , f instead of true , false in functions in r gives me same results. of course, t , f more concise, yet, see true , false being used more often.

i wondering whether there difference between two? there wrong using t , f?

t , f can re-defined, true , false reserved words , cannot re-defined.

> true <- 1l error in true <- 1l : invalid (do_set) left-hand side assignment > false <- 0l error in false <- 0l : invalid (do_set) left-hand side assignment > t <- f  # yikes, hard debug!

personally, use t , f when use r interactively, never use them in production code or packages.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
