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
