I am trying to store regression objects in a data.table df <- data.frame(x = rnorm(20)) df[, "y"] <- with(df, x + 0.1 * x^2 + 0.2 * rnorm(20)) mydt <- data.table(mypower = c(1, 2), myreg = list(lm(y ~ x, data = df), lm(y ~ x + I(x^2), data = df))) mydt #?? mypower??? myreg #???? <num>?? <list> #1:?????? 1 <lm[12]> #2:?????? 2 <lm[12]> But mydt[1, 2]

...unctions you think caused the problem. You could also wrap all the code in a function and use the debugger to step through that (which may help if the error occurs in an iteration of a loop body).

In below graph, I would like to add two vertical lines using panel.abline(). ?Is this possible?

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?

Naresh, I am not sure how you are creating your data.frame so it has no, I think, column names. There are two scenarios including one where it is not really a valid data.frame and one where it can be handled before any other use as shown below. If it cannot be used, you might need to modify how your SQL or the function you call creates it so it includes either names it chooses or that you supply.
