Hi thanks for the help.
Here is the error message i got. I could not figure out what goes wrong here.
======
require(ggplots2)
sampledata=data.frame(c(1.002, 1.76, 0.67, 0.99), c(1.38,1.0,0.5, 0.78), c(1.003,0.57,0.99, 0.58),c(0.76,1.23, 1.45, .78), c(1.43, 1.34, 1.0, 0.9))
rownames(sampledata)=c("cond1", "cond2", "cond3", "cond4")
colnames(sampledata)=c("col1", "col2", "col3", "col4", "col5")
grp=c("grp1", "grp1", "grp2", "grp3")
sampledata=cbind(sampledata, grp)
long.dat=melt(sampledata[,1:5], idvars=as.character(rownames(sampledata)), measure.vars=as.character(colnames(sampledata)[1:5]), variable_name="cols")
ggplot(long.dat, aes(x = cols, y = value)) +
+? geom_line(aes(colour = sampledata$grp)) +
+ facet_grid(~ rownames(sampledata))
Error in get("make_aesthetics", env = x, inherits = TRUE)(x, ...) :
? could not find function "empty"

thanks again,

Hi,
Another easy option would be to convert your data to "long" format and then use ggplot2 or lattice. Something like (though not exact without a reproducible example):
require(ggplot2)
long.dat <- melt(your_data, arguments)
ggplot(long.dat, aes(x = variable, y = value)) +
geom_line(aes(colour = group)) +
facet_grid(~ condition)
HTH,
Josh

Hi friends,
I have a matrix with following format.
group var1 var2 .......varN
c1 group1 1.2399 1.4990....-1.4829
c2 group4 0.8989 0.7849.....1.8933
...
...
c100 group10 .....
I want to draw a profile plot
of each condition c1 to c100, which rows in above matrix and each line
representing a row should be uniquely colored according to the group(1
to 10).
I think this is simple task but I could not figure out how to set the colors.
Any help would be appreciated.
thanks
