Hello,
The following strategy works with your data.
It uses the fact that most dates are in one of 3 formats, dmy, mdy, ymd.
It tries those formats one by one, after each try looks for NA's in the
new column.
# first round, format is dmy
DFX$dnew <- lubridate::dmy(DFX$ddate)
na <- is.na(DFX$d
Hi All,
I have a data frame where one column is a mixed date format,
a date in the form "%m-%d-%y" and "%m/%d/%Y", also some are not in date format.
Is there a way to delete the rows that contain non-dates and
standardize the dates in one date format like %m-%d-%Y?
Please see my sample data
As a follow-up to Michael's post, here is a link to some advice on how
create the example.

Hello,
The function I included converts signed binary numbers into their
decimal representation. They are negative if a) they are multiples of 8
bits and b) the most significant bit is a "1". If not just convert to
integer.
As for a) above, I assume that you will have 8 bit numbers. And the
Dear Rui,
Based on the rules given in the link below, I want to transform the binary
numbers into latitude and longitude coordinates (in degrees and minutes),
so that is basically what I am trying to accomplish. The first integer
gives the sign (positive or negative) of the number, and the rest n-
Example of conversion to decimal of a signed binary number in two's

Let's convert to decimal the following signed binary number: 10110010
10110010 = -1×27 + 0×26 + 1×25 + 1×24 + 0×23 + 0×22 + 1×21 + 0×20 = -128 +

Hope you are doing great, thanks for your kind feedback. The challenge I

Dear James
Your question really boil down to whether you can estimate tau^2, the
between study variance of the effect sizes, if you only have p-values.
As far as I can see the answer has to be no.

Normally one uses match.fun to avoid such problems.
This will give the error shown even if FUN is defined in the global environment.
