I used Anaconda to install R on my Windows pc. From lattice package, show.settings() function causes R session to end. How can this problem be analysed?

In below graph, I would like to add two vertical lines using panel.abline(). ?Is this possible? Thanks, Naresh mydf <- data.frame(hour = rep(6:20, 2), traffic = c(round(dnorm(6:20, 9, 3) * 10000), round(dnorm(6:20, 17, 4) * 10000)), direction = rep(c("inbound", "outbound"), c(15, 15))) vehicles <- data.frame(hour = 6:20, count = c(100, 120, 140, 125, 105, 80, 70, 75,

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? Thanks, Naresh Sent from my iPhone

For below data, I find strange results in basic time series analysis. Why does acf() function find missing values? When crossprod(xmat) is invertible, why does arima() find system exactly singular?

R CMD check <package> gives me below message at the end. There does not seem to be a problem with my TeX installation. Is it possible that R CMD check is not looking in the correct location? How can this problem be fixed? Thanks, Naresh * checking PDF version of manual ... WARNING LaTeX errors when creating PDF version. This typically indicates Rd problems. LaTeX errors found: ! LaTeX

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
