Question

Write the code to return the output:

Code:

id <- c(5, 6, 7, 8, 9)

prod <- c("F", "H", "B", "S", "D")

units <- c(12, 19, 44,26, 43)

df <- data.frame(id, prod, units)

Output must be:

[1] 12 19 44 26 43

Answer #1

id <- c(5, 6, 7, 8, 9)

prod <- c("F", "H", "B", "S", "D")

units <- c(12, 19, 44,26, 43)

df <- data.frame(id, prod, units)

##below line is the answer

df$units

Write the code to return the output: Code: mylist <-

Write a C++ program to demonstrate thread synchronization. Your
main function should first create a file called synch.txt. Then it
will create two separate threads, Thread-A and Thread-B. Both
threads will open synch.txt and write to it. Thread-A will write
the numbers 1 - 26 twenty times in nested for loops then exit. In
other words, print 1 - 26 over and over again on separate lines for
at least 20 times. Thread-B will write the letters A - Z...

Using the predict function in R, find each of the following
predicted values of D, for the given value of C regardless of
whether or not it is appropriate to do so. In real life you should
not calculate for predictions when it is not appropriate, but this
is just for practice.

Find when C = 4
Find when C =...

The data in below table lists country code and the order to
remittance (OTR) time for hardware / software installations for the
last 76 installations (from first to last). OTR is the time it
takes from an order being placed until the system is installed and
we receive payment (remittance). Because this company does business
internationally, it also notes the country of installation using a
country code. This code is listed in the first column.
Table: Country Code and OTR...
