Hi,
I am not getting any errors.
data_chir <- read.table(text="N1_re N2_re N3_re
yes no no
no yes no
na yes yes
no na no",sep="",header=TRUE,stringsAsFactors=FALSE,na.strings="na")
library(reshape2)
melt(data_chir, measure.vars=c("N1_re", "N2_re"), var="zpd")
? N3_re?? zpd value
1??? no N1_re?? yes
2??? no N1_re??? no
3?? yes N1_re? <NA>
4??? no N1_re??? no
5??? no N2_re??? no
6??? no N2_re?? yes
7?? yes N2_re?? yes
8??? no N2_re? <NA>

sorry, I forgot that.. the variables look like this: N1_re N2_re N3_re yes no no no yes no na ye yes no na no 2013/11/23 arun <smartpink111 at yahoo.com> Hi,
You need to make a reproducible example for others to understand the error.?
?set.seed(49)
?data_chir <- data.frame(N1_re=sample(c(NA,"yes","no"),100,replace=TRUE),N2_re=sample(c(NA,"yes","no"),100,replace=TRUE),stringsAsFactors=FALSE)
?melt(data_chir, measure.vars=c("N1_re", "N2_re"), var="zpd") #no errors here.

I want to make a stacked bar plot with one bar for two variables from my
data "chir", the two variables have about 100 values like no, yes and na. I
want to show how many no, yes and na they both have together with the
stacked bar. I tried to melt these to variables first like this:
melt1=melt(data_chir, measure.vars=c("N1_re", "N2_re"), var="zpd")
but it says " arguments imply differing number of rows: 98, 196"
maybe there is another way to make the plot without melt?
thanks in advance!
