aggregate function with a dataframe for both "x" and "by"
...quot; each row of the data is in. I wish to aggregate
each column in mydata using the corresponding column in mybys.
Please see the example below. What is a more elegant or "better" way to
accomplish this task?
Thanks!
mydata = data.frame(testvar1=c(1,3,5,7,8,3,5,NA,4,5,7,9),
testvar2=c(11,33,55,77,88,33,55,NA,44,55,77,99)
)
mybys=data.frame(mbn1=c('red','blue',1,2,NA,'big',1,2,'red',1,NA,12),mbn2=c('wet','dry',99,95,NA,'damp',95,99,'red',99,NA,NA)
, stringsAsFactors =F)
myaggs <- data.frame(matrix(data=NA,...

Tip/Question about encoding temporary data for storage in Asterisk variable to use in AGI
...your base64 encoded object is small!
The following is a simple example which just encodes and decodes the agi
variables themselves as they're an object in ts-agi
(I'm using the ts-agi node package here as an example -
https://github.com/sergey12313/ts-agi/ )
await ctx.setVariable('testvar2',
Buffer.from(JSON.stringify(ctx.variables), 'utf8').toString('base64'))
const testvar2 = (await ctx.getVariable('testvar2')).value
const decoded = JSON.parse(Buffer.from(testvar2,
'base64').toString('utf8'))
console.log('decoded is',...

aggregate.data.frame - prevent conversion to factors? show statistics for NA values of "by" variable?
...there a way to prevent this, and to instead have them retain the format in the original "mybys" data.frame (i.e to have them come back formatted as "character"? Or do I just need to re-format them once I have my results?
mydf=data.frame(testvar1=c(1,3,5,7,8,3,5,NA,4,5,7,9), testvar2=c(11,33,55,77,88,33,55,NA,44,55,77,99) )
str(mydf)
#
myby1=c('red','blue',1,2,NA,'big',1,2,'red',1,NA,12)
myby2=c('wet','dry',99,95,NA,'damp',95,99,'red',99,NA,NA)
myby1.new = ifelse(is.na(myby1)==T,"is_na",myby1)
myby2.n...
