Mail discussion November 2015

Suggestion to suppress RMySQL's lengthy warnings concerning data type changes.

logsr <- suppressWarnings(readdbproduct(440320, "raw_flow_yearly")) %>%
    filterworldeu28()
logsv <- suppressWarnings(readdbproduct(440320, "validated_flow_yearly"))

quicksummary <- function(dtf, reporter_ ,minyear){
    dtf %>% 
        filter(year>=minyear & reporter == reporter_) %>% 
        filter(flow %in% c("Import", "Export")) %>%
        group_by(flow, year) %>% 
        summarise(q = sum(quantity, na.rm=TRUE))
}

logsr %>% quicksummary("Slovakia", 2013)
logsv %>% quicksummary("Slovakia", 2013)
