r - how do you convert df to json file with numbers as number -

-

i trying convert data frame json format. data frame called x:

structure(list(desc = c("web", "mobile", "tv", "store"), total = c(223786915,  42053151, 232299534, 26317530), name = c("total login", "total login",  "total login", "total login")), .names = c("desc", "total", "name" ), row.names = c(na, 4l), class = "data.frame")

this function:

servers <- split(x,x$name) dumfun <- function(x){   sdata <- servers[x][[1]]   if(nrow(sdata) >0){     # create appropriate list     dumlist <- unname(apply(sdata[,c(1,as.numeric(2))], 1, function(y) unname(as.list(y))))     return(tojson(list(name = x, data = dumlist)))    } } jsdata <- lapply(names(servers), dumfun) jsind <- sapply(jsdata, is.null) p<-paste(jsdata[!jsind], collapse = ',') p<-paste('[', p, ']')

it treating x$total string. need x$total number , don't have double quotes around it. ideas might doing wrong?

does jsonlite want?

for example can jsonlite::tojson(x)

res <- jsonlite::tojson(x, pretty=true) cat(res)  [ {     "desc" : "web",     "total" : 223786915,     "name" : "total login" }, {     "desc" : "mobile",     "total" : 42053151,     "name" : "total login" }, {     "desc" : "tv",     "total" : 232299534,     "name" : "total login" }, {     "desc" : "store",     "total" : 26317530,     "name" : "total login" } ]
