Thank you Jeff and Rainer. I will try Jeff's idea using the sub
string. function to extract the year and split on that.
Thanks again to both--EK

In your sample data.frame, MyDate and MyDes are factors; is that what you want?

Couldn't you just use the substr function to pull the year out yourself to make
the grouping column?

Hi All—
I have a data frame with over 13000 rows and 4 columns. A mini data
frame is given at the bottom. I want to split the data frame into
lists each corresponds to single year which ranges from 1990 to 2018).
I wanted to use the split function, but it requires a vector of the
same length as My

Your pattern seems ... way overboard? Why not

If you want to remove just the hyphen, why not do
sub("-", "", tb2a$TID)
sub("-", "", "73-017323")
[1] "73017323"
Am I missing something?

Is the pattern supposed to mean something besides the "-" you want to
remove? For the problem you describe, pattern="-" should be enough. It

You generally only want the patched version if it is known to fix something
that you need. As 3.5.3 is intended as the wrap-up release of 3.5.x, it is
quite likely that the two will only ever differ by name.

Good morning.
This may have already been asked, if so my appologies.
I want to upgrade to 3.5.3 however there is an alternative called patched.
Do I want it or the basic 3.5.3?
Thank you.

You mean, a box per every possible ATTRIBUTE value? This is easily
doable with the bwplot() function from library(lattice).

Hi Bert,
Good reference and David Urbina's example showed that a simple swap
was position dependent. The reason I pursued this is that it seems
more efficient to sequentially apply the precedence rules to the
arbitrarily sorted elements of the vector than to go through the
directed graph approach.
Thank you!
I even bought a manual on this and such feature was not there. Case solved.
Regards,
Luigi

Dear Community,
In our current research we are trying to fit Generalized Additive Models to a

Our dataset contains about 22 million records with less than 20 risk factors
