Suppose we define myvec below. Which of the following blocks of R code will yield the vector $[2-996-9910]?$

myvec $<-$ c$(1,2,3,4,5)$

Please try to complete this problem without looking at RStudio $($believe it or not, this will help strengthen your learning retention$)!$

myfunc $<-\backslash ($x$)$ if $($x $\%\%2==0)-99$ else x $*2$

map$\_$int$($myvec$,$ myfunc$)$

myfunc $<-$ function $($x$)$ if $($x $\%\%2==0)-99$ else x $*2$

map$\_$int$($myvec$,$ myfunc$)$

if$\_$else$($myvec $\%\%2==0,-99,$ myvec $*2)$

myfunc $<-$ function $($x$)$ if $($x $\%\%2==0)-99$ else x $*2$

map$($myvec$,$ myfunc$)$
