[R] fitting an exp model

Hello there, I am trying to fit an exponential model using nls to some data. #data t - c(0,15,30,60,90,120,240,360,480) var - c(0.36,9.72,15.50,23.50,31.44,40.66,59.81,73.11,81.65) df - data.frame(t, var) # model # var ~ a+b*(1-exp(-k*t)) # I'm looking for values of a,b and k #

[R] Calculate AUC Using the Trapezoidal Method

Hello, I want to use function AUC {MIfuns} but I have problem with arguments. My data: Fraction Time Variable C1 0 0.0 C1 15 20.95475 C130 28.55030 C160 36.33064 C190 48.80438 C1 120 60.18636 AUC(data, time = Time, id = Fraction, dv = Variable) ##this is not working!

[R] ANOSIM boxplot problem

Hello! I have a binary data from DGGE gel with 20 samples. These samples are divided into 4 groups, so there are 4(groups) x 5(replicas) = 20. I used ANOSIM method, and everything is ok but ... I have a problem with boxplot... like this: distance - vegdist(dgge2,
