Hello guys, first of all i want to apologise in case i ask for anything i should not to ask.
It is my first time here and i dont know well the rules.
After that, i wanna present myself, im a first year Data Science and Engineering Student (I study in Madrid-Spain, so my english is broken, sorry for that)
I have an asignment that i have to do in RStudio, the assignment its related with the survivors of the titanic
they give me a table with the information of every passenger , their ticket price, they cabin, class of their ticket, etc
The table is something like this:
I attach the file with the table named ("titanic_train.Rdata")
and i have to ask questions related with that information and correlate the data and show the answer with frequency plots, histograms, density plots, scatter plots, boxplots and line plots
The question i have choose to develope for this assignment are:
# Q1: having family members on board (whether siblings, spouses, children or parents) had more chances of survival?
# Q2: People who payed for a Cabin had more probabilities of survival?
# Q3: The Ticket class is related with more probabilities of survival?
# Q4: The number of the ticket is related with more probabilities of survival?
# Q5: Sex, age and class are variables that increases the possibilities to survive?
And the code for the Q1 is:
load("titanic_train.Rdata")
head(titanic.train)
aux=titanic.train$Parch == 0 & titanic.train$SibSp == 0
travels_alone = rep("No", length (aux))
travels_alone[aux] = "yes"
titanic.train = cbind(titanic.train, travels_alone)
prop.table(table(titanic.train$travels_alone, titanic.train$Survived), margin = 1)
library (ggplot2)
ggplot (data=titanic.train)
ggplot(titanic.train) + aes(x = travels_alone, fill = Sex) +
geom_bar(position = position_fill())
and the barchart i got is this
How can i continue with the Questions? It is being so harsh for me to plot the 1 question and i dont even know if its correct.
Can somebody help me?

| Survived | Pclass | Sex | Age | SibSp | Parch | Ticket | Fare | Cabin | Embarked |
| 1 / 0 1 = yes 0 = no | 1 / 2 / 3 | Male / Female | Age in years | number of siblings or spouses aboard the Titanic | number of parents or children aboard the Titanic | Ticket number | Passenger fare | Cabin number | Port of Embarkation (C = Cherbourg, Q = Queenstown, S = Southampton) |
