Hi I have been looking around for a couple of days without being able to find a solution. I am trying to plot the following table using the package ggplot2 Month Mean SEM cry3m 3 -0.05227273 0.1607422 cry6m 6 0.65826087 0.6638734 cry1y 12 0.38333333 0.3062907 cry2y 24 1.04811111 0.4921863 cry3y 36 0.88777778 0.5122407 cry5y 60 -1.22235294 1.1307222 cry7y 84 1.43454545 1.2690701 cry10y 120 0.500000 1.5101821 cry13y 156 0.165000 7.1850000 using the following code: graph<- ggplot(data=NULL, aes(table[,1],table[,2]))+ geom_line(data=NULL, aes(table[,1],table[,2]), color="gray60") + geom_errorbar(aes(ymin=mrsa, ymax=mrsa+semrsa), width=.35, color="gray60")+ graph The line starts obviously at 3 month, I have tried rbind to add a first line of zeros but since I am putting Error bars in the graph the ggplot renders an error. The data used for errorbars is: mrsa cry3m cry6m cry1y cry2y cry3y cry5y cry7y cry10y cry13y -0.05227273 0.65826087 0.38333333 1.04811111 0.88777778 -1.22235294 1.43454545 0.50000000 0.16500000 semrsa cry3m cry6m cry1y cry2y cry3y cry5y cry7y cry10y cry13y 0.1607422 0.6638734 0.3062907 0.4921863 0.5122407 1.1307222 1.2690701 1.5101821 7.1850000 Any help or reading suggestion in solving this problem would be appreciated -- Thanks in advance Maziar Mohaddes MD, Gothenburg, Sweden [[alternative HTML version deleted]]
