Hi there: I am new to R and creating a boxplot panel chart to show a test result.
I have four output variables (OV1, OV2, OV3, OV4) reflecting effects of the variation of three status parameters (SP1, SP2, SP3) on them at three different locations (Loc1, Loc2, Loc3). My plan is that displaying ONE OV change with ONE SP over three Loc in each boxplot (i.e., Loc is X axis and OV value is Y axis). Because there are three SP, I may need total of 12 boxplots to show the changes of OVs with SPs. However, I met a problem when I used the following R code: p1 <- ggplot(OV.m, aes(Loc, value, ymin=value, ymax = value, colour="grey20"))+ + scale_colour_identity()+facet_grid(variable~.,scales="free",as.table=FALSE)+ + theme_bw()+opts(panel.margin=unit(0,"lines") where variable is the title of a column in OV.m (OV.m is melted from OV, original data table); value is OV value for different SP. After I used p2 <- p1 + geom_boxplot(), I found R calculated each boxplot across range of OVs instead of calculating boxplot by OV1, OV2,... , OV4 individually. I only got three boxplots instead of 12. Can any body tell me how to make OV boxplot by OV1, OV2, OV3, OV4 and SP1, SP2, SP3?
