If you complain to the doctor that it hurts when you ram your head into the
wall, (s)he is going to tell you to not so that. What do you expect us to say?
You seem full of misinformation. The apply family functions do not necessarily
speed anything up... they are just more compact than for loop
Hello,
I have a slight performance issue that I'd like to solve by rewriting a
short bit of code that uses for loops so that it would use apply in order
to get some performance gains. My problem is that I can't modify the
variables that are passed to apply function during apply functions
execution
You are entitled to your opinion, but apparently you have not read the Posting

Dear Jean,
Thank you so much for your reply and the solution, This does work. I was
wondering is this similar to 'rasterFromXYZ'? Thanks again!
Sincerely,

Hello everyone,
I am attempting to link to a C library named libxlsxwriter
(http://libxlsxwriter.github.io/) that creates and styles XLSX files, but after
several days of repeatedly reading "Writing R Extensions", and I am stuck and
hoping someone can help me.
The C library is easy to use and wo

Dear Peter
Have you tried removing the intercept? Just put -1 at the end of your
formula.

approx() has a 'rule' argument that controls how it deals with
extrapolation. Run help(approx) and read about the details.

Thanks, Ismail.
For the gaps before 2009-01-05 and after 2009-11-20, I use the year 2010 to
fill in the missing values for column C. There is no relationship between
column A, B, and C.
For the missing values between 2009-01-05 and 2009-11-20, if there are any,
I found this approach is very helpful

Milu,
Perhaps an approach like this would work. In the example below, I
calculate the mean GDP for each 1 degree by 1 degree.
temp$long1 <- floor(temp$longitude)
temp$lat1 <- floor(temp$latitude)
temp1 <- aggregate(GDP ~ long1 + lat1, temp, mean)
long1 lat1GDP

Hi lili,
The problem may lie in the fact that I think you are using
"interpolate" when you mean "extrapolate". In that case, the best you
can do is spread values beyond the points that you have. Find the
slope of the line, put a point at each end of your time data
(2009-01-01 and 2009-12-31) and us
also it's lubridate, not lubricate :-/

If I understand you correctly, that should do it:
