Comment combiner deux graphiques en utilisant R

Quand nous utilisons le logiciel R, c’est très facile de générer un graphique avec la fonction plot(). Mais, quelquefois, nous voulons présenter deux graphiques (ou même quatre) qui montrent des situations différentes, pour les comparer.

Can a Book Make You Rich? (I)

Managing works and projects is the daily task of every engineer. Although we also deal with costs in this management, we often do not apply such knowledge in our personal financial management. In that sense, there are several books on the subject, and one of them is “I will teach you to be rich” of the author Ramit Sethi (you can visit his website clicking here).

Ramit Sethi began by investing his first salary from his scholarship into stocks… resulting in his first loss (he lost half of his investment). That way, he realized that he could not simply invest, he would have to understand how the system works.

Comparing number of users in social medias

Everyone uses them. I don’t deny it, but I use them myself. Facebook, twitter, instagram and many others. There are even people who earn money using them.

I always enjoyed creating lists. Games that I want to play. To do lists. Books I already read and I want to read. The last, I used Skoob to keep my reading records, I registered many books and wrote some reviews.

However, as time goes by, I had to prioritize other things and I never returned there.
Even though my Skoob profile is outdated, I still buy many books. Obviously. Some of these books have changed the way I think and then I decided to share them with you.

(If you are older than 30 years, there is no problem; it is never too late to change).

Les Couleurs des Sols

Les couleurs des sols sont trop utilisées pour leur classification et description et elles sont décrites par le système de couleur créée par Albert H. Munsell.
