R help - Jun 2007 - Removing Inf and Inf values from a fata frame

Hi,

    I have a csv file with empty values, when I apply
the different functions (mean, std, etc.) I create a
new data frame, the empty values generate Inf and -Inf
values. How can I remove those Inf and -Inf values
from the new data frame? I already specified na.rm in
the mean and std functions, but the values are still
there.

Thank you,

Judith

Hi,

try with df[!is.infinite(your_column_in_d.f.),]

?is.finite

for removing the Infs *from the dataframe*, this does not aviod creating 
them by mean() or std().
