ugent questions

Dear everyone,

Would you please help me with these problems that I can't get result
so far.

Questions 1. 2. , I use R.
thank you

1. I read data file to table, but I can't use log to transform it.
I have checked the data, all of them are numeric.

> log(data.frame(data))
Error in Math.data.frame(x) : Non-numeric variable in dataframe: V7

> data$V7
[1] 0.084724 0.000829 0.011257 0.044392 0.002011 0.091450 0.104913
0.080557 0.043877 0.045708 0.016375 0.013757 0.115212

2. problem of box plot

> boxplot(data.frame(data[,1],data[,10]))
Error in if (any(out[nna])) stats[c(1, 5)] <- range(x[!out], na.rm =
TRUE) :
missing value where TRUE/FALSE needed
In addition: Warning messages:
1: "+" not meaningful for factors in: Ops.factor(x[floor(d)],
x[ceiling(d)])
2: "<" not meaningful for factors in: Ops.factor(x, (stats[2] - coef *
iqr))
3: ">" not meaningful for factors in: Ops.factor(x, (stats[4] + coef *
iqr))

3. ANOVA model has a lot of outliers and can't get the result.

Have a good week end
