Value-based color scheme for year-by-year histograms in R

Does that help Using ggplot, to control the color, the easiest way is to get a variable into the data frame which indicates which group it is a part of (the within or outside reference range group). This can be accomplished by a series of steps. First, for each case, match up the appropriate limits based on the year.

code :

Gboth <- merge(Gval2, Gref2, by.x="Year", by.y="REFERENCE_YEAR")

Gboth$within <- factor(Gboth$REFERENCE_LOW < Gboth$Value & 
                       Gboth$Value <= Gboth$REFERENCE_HIGH,
                       levels = c(FALSE, TRUE),
                       labels = c("Outside reference range",
                                  "Within reference range"))

ggplot(Gboth, aes(x=Value)) +
  geom_histogram(aes(fill=within), binwidth=10) +
  facet_wrap( ~ Year) +
  scale_x_continuous("Glucose Levels in mg/dl") +
  scale_y_continuous("Frequency") +
  scale_fill_manual("", breaks=c("Outside reference range", 
                                 "Within reference range"),
                    values = c("black", "red")) +
  opts(title = "Distribution of Glucose Levels")

How to calculate current school year based on two-digit starting year?

This might help you I'd say you're off to a good start. All you need to do is fix the wrap-around issue by adding 100 to the difference if it's negative:

code :

$yr = substr($_SESSION["username"], 1, 2);    
$cur = date("y");  // two-digit year
$diff = $cur - $yr;
if ($diff < 0) $diff += 100;

this one helps. Have you tried using a collection method to constrain what brands are used in the foreach? IE:

code :

@foreach($brands->where('pid', $detail->product_id) as $brand )
    <span>{{$brand->name}}</span>
@endforeach

How to get the product of one and every third integer that is less than a given limit starting with 3 - EXCEPT those div

By : verycrazy

this one helps. If the limit be 21. The output should be 18*12*9*6*3*1. This is what I got so far. , Here’s a method that I believe does what you want.

code :

public double findProduct(int limit) { 
    double product = 1;
        for(int n = 3; n < limit; n = n + 3) {
            if (n%5 != 0)
        {
                product = product * n;
            }
       }
    return product;
}
