There is no way to know what you have done and what did you get: I don't have access to your data. However, variable name You only have one explanatory variable ( |
Many thanks for your quick reply Jari. I am attaching the script and the files. com <- read.csv ("Community.csv", header=TRUE, sep = ";") Year <- read.csv ("Year.csv", header=TRUE, sep = ";") Period <- read.csv ("Period.csv", header=TRUE, sep = ";") rainfall <- read.csv ("Rainfall.csv", header=TRUE, sep = ";") Tmean <- read.csv ("Tmean.csv", header=TRUE, sep = ";") ############## #Testing the significance of each component #Anova Year #Anova Period anova(rda(com.hel ~ as.matrix(Period) + Condition(as.matrix(Year)) + Condition(as.matrix(rainfall)) + #Anova Rainfall #Anova Temperature #Testing the Period individually Many thanks |
Hi everyone,
I hope you can help.
I am testing the effect of Period (Autumn, Winter, and Spring), Year, Rainfall, and Average temperature in a bird passerine community using the function var par. When I have tested the effect of Period in the community (ANOVA), it has been always significant, and when I compare each of the most abundant bird species with Period, the effect of Period has been always significant. So, I am surprised when I used the code below and the result was the Perid being non-significant . So, for that reason, I think I must be doing something wrong. Any advise please?
Anova_period <- (cca(com.hel ~ as.matrix(Period) + Condition(as.matrix(Year)) + Condition(as.matrix(rainfall)) +
Condition(as.matrix(Tmean))))
anova(Anova_period, by="terms", model = "direct")
Many thanks
