Using magrittr and lapply to divide a column in each df in a list by a list of values

will help you If you put the count step in your data_bin step I think it accomplishes what you want, though I am a little hazy on exactly what you mean but I think this works: (Note that you can remove the . assignment from the first argument of lapply, that's the default behavior of %>%)
code :
data_bin <- data_list %>%
 lapply(group_by, temp_bin) %>%
 # We need x so I put summarize in a manual function
 lapply(function(x){summarize(x,n = 5*n()/nrow(x))}) # move the 5 to numerator

Source: local data frame [4 x 2]

  temp_bin         n
1        1 0.7142857
2        2 1.0714286
3        3 1.4285714
4        4 1.7857143
data_bin <- data_list %>%
 lapply(group_by, temp_bin) %>%
 lapply(function(x){summarize(x,n = nrow(x))}) 

Source: local data frame [4 x 2]

temp_bin  n
1        1 14
2        2 14
3        3 14
4        4 14

Using *ngFor to populate a radio list formatted across 3 divs

hop of those help? Did a few things...
First, i added the bootstrap css file to index.html next to distribute the 'dynamic' radio buttons into 3 divs, we can take advantage of column-count property of CSS; while to distribute the 'fixed' options a,b,c... we can use bootstrap class of col-md-4;
code :
<div  >
    <div class="myColumns" >
        <div class="form-check" *ngFor="let item of MajorExposureItems; let i = index">

  <div class="row">
    <div class="col-4 col-md-4">a </div>
    <div class="col-4 col-md-4">b</div>
    <div class="col-4 col-md-4">c</div>
.myColumns{-webkit-column-count: 3; /* Chrome, Safari, Opera */
  -moz-column-count: 3; /* Firefox */
  column-count: 3;}

Iterate through a list, divide values, store in new list

I wish did fix the issue. In the code I have series of lists, each one containing the same number of entries. What I want to do now is iterate through the list and divide one list index by the other. , The better way to do this is to use zip.
You can try this:
code :
avg_vals = []
for thread, dsk_ind in zip(threads, dsk_indpt_PI):
    avg_vals.append(dsk_ind / thread)

How to divide columns in a list by different values stored in another list?

around this issue We can do arithmetic on equal length vectors/matrices/data.frames. One option is to divide each of the elements in list with the colSums replicated to make the dimensions same
code :
lapply(listex, function(x) x/colSums(x)[col(x)])
Map(function(x, y) x/y[col(x)], listex, listtotal)
