Hi!

I'm doing a draft script just before I use it with the real data.

I'm creating an Expressionset, everything goes ok until I get the an error, which I have not been able to solve. I have not seen a solution for this on the internet.

Error en getClass(Class, where = topenv(parent.frame())) :
  “AnnotatedDAtaFrame” is not a defined class

This is the draft script:

library(Biobase)

matriz <- matrix(data = c(seq(16)), nrow = 4, ncol = 4, byrow = FALSE)
rownames(matriz) <- c("Gen 1", "Gen 2", "Gen 3", "Gen 4")

setwd("/home/Escritorio")
list.files()

samples <- read.csv(file = "samples.txt", header = TRUE, sep = "\t", check.names = FALSE)
samples <- as.data.frame(samples)
varInfo <- read.table(file = "meta.txt", header = TRUE, colClasses = "character", check.names = FALSE)

pd <- new("AnnotatedDAtaFrame", data = samples, varMetadata = varInfo)

This is the sessionInfo()

I have update Biobase packages.

Thanks!

Is this a simple typo -- AnnotatedDataFrame rather than ...DAtaFrame ?
