Hi Stefano,
my guess is that you're expecting data recycling to apply but your
data frame is only one row long... therefore you can't insert a 2-row
vector into a 1-row vector. Recycling won't help.
You should specify the number of rows that will be required in your
data frame using (e.g) rep().

2) Your data frame has one row, with an NA in the date_POSIX column. You cannot
fit a vector of length 2 as a column into a data frame with only 1 row.
What are you trying to do? Do you really want to end up with a 2-row data frame

Dear R users,
I know that this question is silly (I am not a R newby) but I already wasted
quite a lot of energies trying to fill in an empty data frame (with "POSIXct"
"POSIXt" data type).
Suppose I create
mydf <- data.frame(data_POSIX=as.POSIXct(NA), value=as.numeric(NA))
day1 <- as.POSIXct("2
