Sorry Maryam but I use neither reshape nor ggplot2 so I will leave it to
others to advise you.

Dear Michael,
Thanks for your feedback. Actually, I would like to show (and compare)
size distribution of df1 and df2 in the single plot using ggplot2,
something like the attached picture. The command dosesn't lead me to
this purpose. However, I'm really new here, could you please help
me more on this?
Thanks in advance,
Maryam

Dear Maryam
If you just need all the values of size would
c(df1$size, df2$size)
work?

Dear Sir / Madam,
I have just come to the amazing R software, so please be patient
if my
question is basic for you. I have 2 text file (say 1.txt and
2.txt), each
file containing 2 columns and different row numbers, like below
case size
case1 120
case2 120
case3 121
case4 121
case5 121
case6 122
case7 122
case8 123
I would like to have a one plot for all text files, with x-axis
shows the
size between 300-1200 with the interval of 200
(300,500,700,900,1200) and
size between 1201-1500 with the interval of 1000. For dataframes
with the
equal row numbers, the following codes worked well,
df1 = data.frame("1.txt", header=T)
df2 = data.frame("2.txt", header=T)
*combining two dataframes with equal row number*
df = data.frame(df1$size,df2$size)
library(reshape)
melted <- melt(df)
ggplot(data=melted, aes(value))+aes(fill=variable)+ geom_histogram
(binwidth =500)+
+scale_x_continuous(breaks=c(seq(300,1000,by=200),seq(1001,15000,by=1000)))
but I couldn't reproduce the plot with these codes for
dataframes with
different row number. I think the problem is* how to combine
datafrmaes
with the different row number*, could you please help me out on
this issue?
Thank you in advance
