Create the following variables.
w <- 10.2
x <- 1.3
y <- 2.8
z <- 17.5
dna1 <- "attattaggaccaca"
dna2 <- "attattaggaacaca"
Use them to print whether or not the following statements are
TRUE
or FALSE
.
w
is greater than 10w
+ x
is less than 15x
is greater than y
x
+ 0.2 is equal to y
dna1
is the same as dna2
dna1
is not the same as dna2
The number of occurrences of the base t is the same in dna1
and dna2
Use str_count()
from the stringr
package.
Youâ€™ll need to install this package before using it and will also want to
familiarize yourself with str_length()
.
w
is greater than x
, and y
is greater than z
x
times w
is between 13.2 and 13.5dna1
is longer than 5 bases, or z
is less than w
* x
dna1
and dna2
is greater than or equal to 30w
+ x
+ y
) divided by the logarithm (base 10) of 100 is equal to 7.15dna1
is not the same as
the GC content of dna2
