Hello,
Maybe you need apply, not lapply. It seems you want to apply() a
function to the first dimension of your data.frame, something like
apply(dat, 1, fun) #apply by rows
Hope this helps,

I have a Data Frame that contains, between other things, the following
fields: userX, Time1, Time2, Time3. The number of observations is 2000.
I have a function that has as inputs userX, Time1, Time2, Time3 and return
a data frame with 1 observation and 19 variables.
I want to apply that function to all the observations of the first data
frame to make a new data frame with 2000 observations and 19 variables.
I thought about using lapply, but if I understand correctly, it only takes
one variable.
Can somebody point me in the right direction?
Thanks!
