Here is an example piece of code to illustrate an issue:
rm(list=ls()) # Clear Workspace
#
Data1 <- matrix(data=rnorm(9,0,1),nrow=3,ncol=3)
Colnames1 <- c("(A)","(B)","(C)")
colnames(Data1) <- Colnames1
print(Data1)
DataFrame1 <- data.frame(Data1)
print(DataFrame1)
colnames(DataFrame1) <- Colnames1
print(DataFrame1)
The results I get are:
(A) (B) (C)
[1,] 0.4739417 1.3138868 0.4262165
[2,] -2.1288083 1.0333770 1.1543404
[3,] -0.3401786 -0.7023236 -0.2336880
X.A. X.B. X.C.
1 0.4739417 1.3138868 0.4262165
2 -2.1288083 1.0333770 1.1543404
3 -0.3401786 -0.7023236 -0.2336880
(A) (B) (C)
1 0.4739417 1.3138868 0.4262165
2 -2.1288083 1.0333770 1.1543404
3 -0.3401786 -0.7023236 -0.2336880
so that when I make the matrix with headings the parentheses are replaced by
periods but I can add them after creating the data frame and the column
headings are correct.
Any ideas on why this occurs?
