Using variable value as column name in data.frame or cbind

Question

Is there a way in R to have a variable evaluated as a column name when creating a data frame (or in similar situations like using cbind)?

For example

Answer 1

just use colnames after creation. eg

a <- "mycolA"
b<- "mycolB"
d <- data.frame(a=1:10, b=rnorm(1:10))
colnames(d)<-c(a,b)
d
mycolA     mycolB

 2 -0.4195322
 3 -0.9511075
 4  0.2259858
 5 -0.6619433
 6  3.4669774
