If you don't get a satisfactory answer here in due course, you can try
contacting the package maintainer, who you can find via ?maintainer.

Dears,
I use the R library highcharter with ubuntu 18.04 and R 3.6.3. Recently, I

I was able to adapt your solution using packages with which I am more familiar.
myres2 <- merge(option.trades, stock.trades, by = "timestamp", all =
TRUE)
myres2[,"stock.timestamp"] <- ifelse(is.na(myres2$stock.price), NA,
myres2$timestamp)
myres2$stock.timestamp <-
Hi Naresh,
Perhaps the below is faster than your approach
library(dplyr)
library(tidyr)
merge(option.trades, stock.trades, by="timestamp", all=TRUE) |>
dplyr::arrange(timestamp) |>
dplyr::mutate(stock.timestamp =
as.POSIXct(ifelse(is.na(option.price), timestamp, NA))) |>
