Hi Naresh Gurbuxani, There are already several answers dealing with the specific code that you wrote, but my reaction is to step back a little.

I have written a function which returns an SQL query result as a data.frame. Each column of data.frame is a variable not explicitly defined. For every column name, R CMD check says ?no visible binding for global variable <name>. Status: 1 NOTE Is it possible to tell R CMD check that these variables are OK?

On converting character variables to ordered factors, regression result has strange names. Is it possible to obtain same variable names with and without intercept? Thanks, Naresh mydf <- data.frame(date = seq.Date(as.Date("2024-01-01"), as.Date("2024-03-31"), by = 1)) mydf[, "wday"] <- weekdays(mydf$date, abbreviate = TRUE) mydf.work <- subset(mydf, !(wday

This code gives unexpected result. library(data.table) library(lattice) set.seed(123) mydt <- data.table(date = seq.Date(as.IDate("2024-01-01"), by = 1, length.out = 50), xgroup = "A", x = runif(50, 0, 1)) mydt <- rbindlist(list(mydt, data.table(date = mydt$date, xgroup = "B", x = runif(50, 0, 3)))) mydt[, `:=`(xcumsum = cumsum(x)), by = .(xgroup)] mydt[,
