Re: [R] Functional Programming Problem Using purr and R's data.table shift function

[Michael Lachanski]

Dénes, thank you for the guidance - which is well-taken.

Your side note raises an interesting question: I find the piping %>%
operator readable. Is there any downside to it? Or is the side note meant
to tell me to drop the last: "%>% `[`"?

Thank you,

Hi Mukesh,

 

Have a look at the blurb that prints at the start-up of R.


"R is free software and comes with ABSOLUTELY NO WARRANTY."

 

This is a hint that the R-Project is unlikely to be issuing certificates.

Re: [R] R Certification

[Spencer Graves]

	  If you go to "https://cran.r-project.org"; and click, "Download R for 
macOS", you will find several versions that you can download and that 
have a "digital signature".



	  After downloading, you can "check the integrity of the downloaded 
package by checking the signature: pkgutil --check-signature R-4.2.2.pkg".



	  Beyond that, RStudio and other companies will happily sell you a 
maintenance contract, which will get you more polite answers than from a 
list serve like this ;-)

Hello Jeff !

Yes, you are right.. and that’s why I am asking this question - just

like other

governing bodies that issue certification on their respective

technologies, does

"r-project.org" also have a learning path ? and then a certification.

Say - Microsoft issues certificate for C#, .Net, etc..
Then, Oracle issues certificates for Java, DB etc..

These are authentic governing bodies for learning and issuing

certificates


On exactly similar lines -  "r-project.org" would also be having some

learning

path and then let "r-project" take the proctored exam and issue a

certificate...


I am not looking at any external institute for certifying me on "R" -

but, the

governing body itself..

So, the question again is - "does r-project provide a learning path and

issue

certificate after taking exams"

I think this request is like saying "I want a unicorn." There are many
organizations that will enter your name into a certificate form for a

fee, possibly

with some credibility... but if they put "r-project.org" down as the

name of the

organization granting this "certificate" then you are probably getting

fooled.

Re: [R] R Certification

[PIKAL Petr]

Hallo Mukesh

R project is not Microsoft or Oracle AFAIK. But if you need some certificate 
you could take courses on Coursera, they are offering certificates.

Cheers
Petr

Re: [R] R Certification

[Mukesh Ghanshyamdas Lekhrajani via R-help]

Hello Jeff !

Yes, you are right.. and that’s why I am asking this question - just like other 
governing bodies that issue certification on their respective technologies, 
does "r-project.org" also have a learning path ? and then a certification.

Say - Microsoft issues certificate for C#, .Net, etc..
Then, Oracle issues certificates for Java, DB etc..

These are authentic governing bodies for learning and issuing certificates 

On exactly similar lines -  "r-project.org" would also be having some learning 
path and then let "r-project" take the proctored exam and issue a certificate...

I am not looking at any external institute for certifying me on "R" - but, the 
governing body itself..

So, the question again is - "does r-project provide a learning path and issue 
certificate after taking exams"

Thanks, Mukesh

I think this request is like saying "I want a unicorn." There are many 
organizations that will enter your name into a certificate form for a fee, 
possibly with some credibility... but if they put "r-project.org" down as the 
name of the organization granting this "certificate" then you are probably 
getting fooled.

Re: [R] R Certification

[Jeff Newmiller]

I think this request is like saying "I want a unicorn." There are many 
organizations that will enter your name into a certificate form for a fee, 
possibly with some credibility... but if they put "r-project.org" down as the 
name of the organization granting this "certificate" then you are probably 
getting fooled.

[R] R Certification

[Mukesh Ghanshyamdas Lekhrajani via R-help]

Hello R Support Team,

 

I want to do R certification, could you help me with the list of
certificates with their prices so it helps me to register.

 

I want to do the certification directly from the governing body
"r-project.org" and not from any 3rd party.

 

Please help.

 

 

 

Mukesh
