amazon web services - dynamodb - scan items by value inside array -

-

i'm doing table scan. table has array 1 of fields, "apps" field (apps not key of kind). want select rows, apps array contains value "myapp". tried of kind, syntax incorrect:

    comparisonoperator = "#apps contains :v",     expressionattributenames = {         '#apps': 'apps'     },     expressionattributevalues = {         ":v": "myapp"     }

thanks.

the documentation condition expressions states appropiate syntax is:

contains(#apps, :v)

the correct request be:

filterexpression: "contains(#apps, :v)", expressionattributenames: { "#apps": "apps" }, expressionattributevalues: { ":v": "myapp" }

-
so let's have named vector: sorted = c(1,2,3) names(sorted) = c("a","b","c") and it'll following: > sorted b c 1 2 3 so vector named a,b,c, , has value 1,2,3 respectively. and have sample data: data.ex = as.data.frame(matrix(rep(c(1,2,3,4),3), nrow = 3, ncol = 3)) colnames(data.ex) = c("a","b","c") so data frame has 3 columns named a,b,c well. i want predict c using value in glm(): fit.ex = glm(formula = c ~ names(sorted)[2], data = data.ex, family = binomial(link = "logit")) but then, i'll keep getting following error message: error in model.frame.default(formula = c ~ names(sorted)[2], data = data.ex,: variable lengths differ (found 'names(sorted)[2]') i read article here , found as.name() function, still not working: http://www.ats.ucla.edu/stat/r/pages/looping_strings.htm and cannot find else thats similar problem. please, if the...
