Optimal way to set cell values in Google Sheet via Script - google-apps-script

Question

I have a template sheet with checkboxes and I want to copy the checked ones to a new sheet. I have a working version that involves adding rows but I am looking for something faster. I thought getting a range of values on both the new and old sheets and working on the arrays would be best but I hit a error:
'Cannot covert Array to Object[][]".
I think the issue has to do with the fact that this is a new unpopulated sheet. The code below is the simplest example of what is happening. Am I doing something wrong, or is this just not possible?
function test(){
var s = SpreadsheetApp.getActiveSpreadsheet().insertSheet();
var r = s.getRange(1,1,5);
var v = r.getValues();
for ( var i=0; i < 5; i++) {
v[i] = i;
}
r.setValues(v); //ERROR: Cannot covert Array to Object[][]`enter code here`
}
It looks like the line v[i] = i; converts the Object[][] to an array. So , i think (bizarre) I need to create a new array[][] asfollows:
function test(){
var s = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var r = s.getRange(1,1,5,1);
var v = r.getValues();
var ta = [];
for ( var i=0; i < 5; i++) {
ta[i] = [];
ta[i].push(i) ;
}
r.setValues(ta);
}

Ok. Here is the full solution.
The function looks for the sheet "Work" that has 2 columns; the first is a checkbox, the second is the string value of interest. For every checked box (value == true), the 2nd column's value, Font weight, and Font size are copied into appropriately 'shaped' structures.
Once constructed, a new sheet is created, a range in the new sheet is retrieved and used to set the values, weights and sizes of a single column.
function copyCheckedItems () {
var cl = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Work');
if (cl) {
var cnt = cl.getLastRow();
var range = cl.getRange(1,1, cnt, 2 );
var values = range.getValues();
var weights = range.getFontWeights();
var sizes = range.getFontSizes();
// Compute data needed for new sheet in the right shape.
var tv = [];
var tw = [];
var ts = [];
var newCnt = 0;
for (var row in values) {
if(values[row][0]){
tv[newCnt] = [];
ts[newCnt] = [];
tw[newCnt] = [];
tv[newCnt].push(values[row][1]);
tw[newCnt].push(weights[row][1]);
ts[newCnt].push(sizes[row][1]);
newCnt++;
}
}
// construct the new sheet in a minimum of calls
var name = Browser.inputBox('Enter WorkSteet name');;
var sheetOut = SpreadsheetApp.getActiveSpreadsheet().insertSheet(name);
var ro = sheetOut.getRange(1,1,newCnt,1);
ro.setValues(tv);
ro.setFontSizes(ts);
ro.setFontWeights(tw);
//Browser.msgBox("Done.");
}
else {
Browser.msgBox('Work sheet not found!');
}
}
