paste quotation marks into character string, within a loop

Question

Using R, I want to produce multiple character strings such as:

\"modelCheck(\"var1_d.bug\")\"  
\"modelCheck(\"var2_d.bug\")\"  
...  
\"modelCheck(\"var10_d         


        

Answer 1

Simply escape the quotation marks with backslashes:

paste("modelCheck(var\"",i,"_d.bug\")",sep="")

An alternative is to use single quotes to enclose the string:

paste('modelCheck(var"',i,'_d.bug")',sep="")
