error data frame

Hallo everybody!
I am trying to perform a TiTAN (Baker & King 2010) analysis with R 2.14.1. I
have come that far:

h89Abund <- read.csv("Fish89Abund.csv")

names (Fish89Abund)

[1] "StationCode"                "Abramisbrama"              
"Alburnoidesbipunctatus"     "Alburnusalburnus"          
 [5] "Ameiurusmelas"

Fish89PCA <-read.csv("Fish89PCA.csv")
names (Fish89PCA)

[1] "StationCode" "PCA1"

# Check data (1:X rows, e.g. 1:3,=1.-3.row or else)
Fish89PCA [1:3,]

StationCode       PCA1
1       DE582 -1.5592527
2        DE38  0.3530658
3  FR02116570  2.8057854

names (Fish89PCA)

[1] "StationCode" "PCA1"

Fish89TiTAN <- titan(Fish89PCA, Fish89Abund, minsplt=5,

+ numprm=250, nboot=500, boot=TRUE, deviance=TRUE)
[1] "Taxa frequency screen complete"
[1] "Function definition complete"

Error in is.data.frame(x) : subscript out of bounds

This essror mesage is killing me. I checked the data tables and the
internet, but nowhere any satisfying answer.
Can anybody help me please? Thanks in advance!!
