Data_Manipulation - step_4_titanic not working
I'm not able to pass the step 4 of the Data_Manipulation. Using the answer in
- Data_Manipulation/scripts/step_4_titanic-correct.R
or using skip()
doesn't work.

Reading _Tabular_Data not working past 41% completion
problem is with the read_csv(datafile) step. Need to include show_col_types = FALSE in order to proceed to the next step. putting this in as the answer gets an error, and using the skip() will not resolve it because the correct answer is not working either.

Functional programming: missmatch in map2_chr() example
I think that the assignment:
" Use map2_chr() to apply the paste() function to the sequence of integers from 1 to 26 and all the
letters of the alphabet in lowercase."
And the solution:
"map2_chr(letters, 1:26, paste)"
have the first two arguments inverted
titanic_4 not working
Good day
Further to others that have posted here, I am working on the titanic dataset problem #4 and am having the same issue, where the answer I have (from the titanic_4_corrected file here) is not being marked as Correct.
This is the code I am running:
titanic_4 <- titanic %>%
select(Survived, Pclass, Age, Sex) %>%
filter(!is.na(Age)) %>%
mutate(agecat = cut(Age, breaks = c(0, 14.99, 50, 150),
include.lowest = TRUE,
labels = c("Under 15", "15 to 50", "Over 50"))) %>%
group_by(Pclass, agecat, Sex) %>%
summarize(N = n(),
survivors = sum(Survived == 1),
perc_survived = 100 * survivors / N)
which I realized doesn't have the head(titanic_4) line at the end; however, I'm still not able to get it working and am completely stumped.
Any ideas would be appreciated.
