Hello,
Thanks for the data, it makes things easier.

I reported this behavior on Thu Jan 7, 2021.
You did nothing wrong.
No fix has been issued.
This evening, I upgraded from R 4.0.2 to the Duke University R 4.0.3 for Apple
Mac. Now all I can get from R 4.0.3 is this red error message (that means
nothing to me). Is there an easy fix? Greg

Dear Sir/Madam,
After installing R package version 4.0.3 and launching the R Console for the
first time, below warning message appeared:

Hi Jibrin,
solar_wind_sps<-data.frame(sws=306,date="2021-016")
solar_wind_spd
solar_wind_spd$date<-as.Date(solar_wind_spd$date,"%Y-%j")
solar_wind_spd
This changes the "date" field to an actual date object. If you just
want to change a character string date to another format:
solar_wind_spd$date<

Hi.
Can you upgrade your version of R? That might help.

Hi,
Yes, I don't really know what the maintainer will answer to me. Except that
rgam is no longer on CRAN, that I already know !
However, I know mgcv and "classical" GAM model but GAMs can be very sensitive
to the presence of a small proportion of observations that deviate from the
assumed mode
Use one of the POSIXt classes, POSIXct or POSIXlt, instead of the Date
class.
They have more methods for doing arithmetic. E.g.,
> dates <- as.POSIXct(tz="UTC", c("2004-03-01", "2005-03-01"))
> difftime(dates, trunc(dates, units="year"), units="days") # add 1 if you
want -01-01 to be day 1 in
There are many good tutorials for R. As a "newbie", you need to avail
yourself of them. Although this forum is meant to "help", it is not
designed to provide tutorials. Understanding basic R functionality is
largely assumed here.
Searching on "tutorials on date-time data in R" brought up many

Hello,
No dataset was attached. Like the posting guide says,
No binary attachments except for PS, PDF, and some image and archive
formats (others are automatically stripped off because they can contain

Dear R users,
I am very new to R software. I have solar wind speed data needed for my
work. How do I convert day in the year to year, month, and day with R
software? I have used this code
as.Date(0, origin = "1998-01-01")
but it can only convert one day of the year at a time. Meanwhile, I have up
