[R] Getting warning message

[namit]

Hi Friends,


I  have  a data frame X, and I want to add “%” & “$” in row  4 and 5
respectively. when I’m trying using below logic, I’m getting warning
message.
Can anyone  help me out on this.


X:
Summary	      G	Y	R	T
Accts	     582	644	0	1226
AcctCov	     230	165	0	395
Cov%	      40	26	0	32
UnCov%	     60	74	0	68
EqVol11$MM8.5	10.6	0	19.1

Using this logic: 

Z16[5,2:5]<-paste("$",Z16[5,2:5],sep="")
Z16[3,2:5]<-paste(Z16[3,2:5],"%",sep="")
Z16[4,2:5]<-paste(Z16[4,2:5],"%",sep="")

Getting this Warning: In `[<-.factor`(`*tmp*`, iseq, value = c(3L, 1L, 2L,
4L, NA))
                                            invalid factor level, NAs
generate


Final result:

Summary   G	Y	R	T
Accts	582	644	0	1226
AcctCov	230	165	0	395
Cov%	40%	26%	0%	32%
UnCov%	60%	74%	0%	68%
EqVol11$MM$8.50 	$10.60 	$0 	$19.10 


Thanks in Advance.

Thanks,
Namit
