below are the heading for my data:
Bear ID/ Date DMY/ sighting occurred in morning (0/1)/ time since arrival this dry season (days)

this is a sample of my data:

dput(head(raw_data_1,10))

My apologies if this is extremely basic. I've been trying to teach myself to code through quarantine, so I'm quite new. My goal is to create an if statement that returns each ticker and its corresponding position into certain columns in Excel based on the group the ticker belongs to.

The tickers and positions are contained in a DataFrame I've converted to two lists, I also have converted it to a dictionary. Nothing seems to work to solve the whole problem. My dictionary uses Tickers as keys and Positions as values. My lists contain all Tickers and all Positions. Pasting what is returned from print(dict) below:

so im working with:

I create a dataframe from Yahoo and I want to use Pivot function to categorize the data. I want the index is Date, columns is symbol, value is close.

Any assistance on this little conundrum would be mightily appreciated thanks.

I am trying to pass an argument to the tq_transmute function from the tidyquant package; the value for the argument is a function, however I would like to pass it as a string (out with the scope of the example below I’ll be passing it via a Shiny selectInput).

I have tried every way I can think of to turn the string 'apply.quarterly' into the object apply.quarterly accepted by the mutate_fun argument. The commented lines are my failed attempts.

Ultimately, I would like to extend this concept to the other arguments also i.e. FUN = max to FUN = ‘max’.
