help with e+01 number abbreviations

Dear List,

I will appreciate any advice regarding how to convert the following numbers
[I got in return by taxondive()] in numeric integers without the e.g.
6.4836e+01
abbreviations.
Thank you very much in advance,

Gian

Hi.

The exponential format was used probably due to some small
numbers. For example

?tst <- rbind(
?c( 5.0000e+00, 6.4836e+01, 9.5412e+01, 6.7753e+02, 8.7398e+01, 436.99),
?c( 2.0000e+00, 4.0747e+01, 1.0000e+02, 0.0000e+00, 1.0000e+02, 200.00),
?c( 3.0000e+00, 4.5381e+01, 7.7652e+01, 2.8075e+02, 8.8152e+01, 264.46),
?c( 1e-8, ? ? ? 1e-8, ? ? ? 1e-8, ? ? ? 1e-8, ? ? ? 1e-8, ? ? ? 1 ))

?tst

? ? ? ?[,1] ? ? ? [,2] ? ? ? [,3] ? ? ? [,4] ? ? ? [,5] ? [,6]
?[1,] 5e+00 6.4836e+01 9.5412e+01 6.7753e+02 8.7398e+01 436.99
?[2,] 2e+00 4.0747e+01 1.0000e+02 0.0000e+00 1.0000e+02 200.00
?[3,] 3e+00 4.5381e+01 7.7652e+01 2.8075e+02 8.8152e+01 264.46
?[4,] 1e-08 1.0000e-08 1.0000e-08 1.0000e-08 1.0000e-08 ? 1.00

Try roudning the numbers, for example

?round(tst, digits=4)

? ? ? [,1] ? [,2] ? ?[,3] ? [,4] ? ?[,5] ? [,6]
?[1,] ? ?5 64.836 ?95.412 677.53 ?87.398 436.99
?[2,] ? ?2 40.747 100.000 ? 0.00 100.000 200.00
?[3,] ? ?3 45.381 ?77.652 280.75 ?88.152 264.46
?[4,] ? ?0 ?0.000 ? 0.000 ? 0.00 ? 0.000 ? 1.00

Alternatively, options(scipen=20) forces a fixed point printing
with more digits.

?options(scipen=20)
?tst

? ? ? ? ? ? [,1] ? ? ? ?[,2] ? ? ? ? [,3] ? ? ? ? [,4] ? ? ? ? [,5] ? [,6]
?[1,] 5.00000000 64.83600000 ?95.41200000 677.53000000 ?87.39800000 436.99
?[2,] 2.00000000 40.74700000 100.00000000 ? 0.00000000 100.00000000 200.00
?[3,] 3.00000000 45.38100000 ?77.65200000 280.75000000 ?88.15200000 264.46
?[4,] 0.00000001 ?0.00000001 ? 0.00000001 ? 0.00000001 ? 0.00000001 ? 1.00

Hope this helps.
