How to set a column value based on values in another column in R -


i trying add new column based on values in column. (basically if other column missing or 0, set new value 0 or 1)

what's wrong code below? 

times=nrow(eachfile) for(i in 1:times) {eachfile$salescyclen0[i] <- ifelse(eachfile$r[i]==na | eachfile$r[i]==0,0,1 ) }  table(eachfile$salescyclen0)

as long have tested column contains 0, 1 , na do:

eachfile$salescyclen0 <- 1 eachfile$salescyclen0[is.na(eachfile$r) | eachfile$r==0] <- 0

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!
