...k that there was a significant decrease in soil moisture as I decreased the watering frequency, i.e. watering level 7 showed lower soil moisture units than level 1. I have carried out a repeated measures anova as follows (where block is which time the reading was taken: 1,2,3 or 4): model1<-aov(soilmoisture~wateringlevel+Error(block/wateringlevel)) I then plotted (soilmoisture~wateringlevel) and fitted a regression line: lm1<-lm(soilmoisture~wateringlevel) abline(lm1,lty=1) Here are my questions: 1) Is the repeated measures anova I have entered correct to tell me if there is a significant diff...

Hi All, I am trying to lable the y-axis on my scatterplot with the following: "Soil moisture content (m3m-3)" I am using the following coding for plotting the graph: plot(soilmoisture~gradientlevel, xlab="Levels of droughting gradient", ylab="Soil moisture content (m3m-3)", bty="l", font.main="2", pch=16, las=1, cex.lab="1.13") I have tried to incorporate 'expression' into this coding for the ylab as follows (with also a...
