从 R 中的特殊字符中删除引号

Question

When I print pattern program in r ,

 char<-c("#","@")
m<- matrix(paste(char[1]),nrow  =4, ncol = 4)
print(m)

My output is

 [,1] [,2] [,3] [,4]
[1,] "#"  "#"  "#"  "#" 
[2,] "#"  "#"  "#"  "#" 
[3,] "#"  "#"  "#"  "#" 
[4,] "#"  "#"  "#"  "#" 

But my desired output is # without quotations. I tried char method, I tried vector and I tried noquote function. But none worked for me. If anyone knows the solution, help me to solve.

Answer 1

The double quotes are not actually part of the data and is just how the output is rendered by R; however, if you knew that already and are asking how to print it without the double quotes then use noquote

noquote(m)

giving:

     [,1] [,2] [,3] [,4]
[1,] #    #    #    #   
[2,] #    #    #    #   
[3,] #    #    #    #   
[4,] #    #    #    #   

Also print has a quote=FALSE argument giving the same output:

print(m, quote = FALSE)
