In two weeks, the third year of the Data Science for Actuaries program will start. I will be there for the introduction to R. The slides are available online (created with slidify)

A markdown is also available. I have to thank Ewen for his help on slidify (especially for the online quizz, and the integration of leaflet maps or the rgl animated graph….)

In one of the quizzes the solution is wrong, there is plus sign between 5 and i*j (5+i*j) and not (5*i*j).

s=0; for(i in 1:10) for(j in i:10) s=s+i*i/(5+i*j); s

Another one:
While computing 1:3 * 1:5 there is an error in R
Warning message:
In 1:3 * 1:5 :
longer object length is not a multiple of shorter object length

Hello!
Great presentation!
How did you include googleVis graph in slidify?
When I tried to include Sankey diagram into slidify presentation – nothing happened at all.

Warning message:

In 1:3 * 1:5 :

longer object length is not a multiple of shorter object length

Also (1:3)*(1:5) yield the same error.

In the quizz about the roots of the polynomial

options(digits=3)

polyroot(c(-1,1,1)) gives 0.618 and -1.618

your solution has the wrong signs.

Awesome!

Can we do quizz in ioslides?

Best regards

here it was possible (see http://freakonometrics.free.fr/DSA2017/DSAslides.html#47) but I don’t know with ioslides
