Hi everybody.
I'm looking for the way to increase the depth value in 0.01 for each index
group.
Easier to explain with this example:
>my_data=read.table("clipboard", header=TRUE)
Depth s_name index
3852 Site_1 144
3852 Site_1 144
3852 Site_1 144
3852 site_A 145
3852 site_A 145
3852 site_A 145
3852 site_A 145
3852 site_B 147
3852 site_B 147
3852 site_B 147
3852 site_B 147
54962 site_C 27
54962 site_C 27
54962 Site_D 217
54962 Site_D 217
54962 Site_D 217
54962 Site_D 217
I'm looking for something like that (four column)
Depth s_name index Im_looking
3852 Site_1 144 3852.01
3852 Site_1 144 3852.01
3852 Site_1 144 3852.01
3852 site_A 145 3852.02
3852 site_A 145 3852.02
3852 site_A 145 3852.02
3852 site_A 145 3852.02
3852 site_B 147 3852.03
3852 site_B 147 3852.03
3852 site_B 147 3852.03
3852 site_B 147 3852.03
54962 site_C 27 54962.01
54962 site_C 27 54962.01
54962 Site_D 217 54962.02
54962 Site_D 217 54962.02
54962 Site_D 217 54962.02
54962 Site_D 217 54962.02
Currently I found the way to increase the depth but not like I need,
tave = my_data$Depth + (ave(my_data$Depth, my_data$index, FUN=seq_along))/100
Depth s_name index test
3852 Site_1 144 3852.01
3852 Site_1 144 3852.02
3852 Site_1 144 3852.03
3852 site_A 145 3852.01
3852 site_A 145 3852.02
3852 site_A 145 3852.03
3852 site_A 145 3852.04
3852 site_B 147 3852.01
3852 site_B 147 3852.02
3852 site_B 147 3852.03
3852 site_B 147 3852.04
54962 site_C 27 54962.01
54962 site_C 27 54962.02
54962 Site_D 217 54962.01
54962 Site_D 217 54962.02
54962 Site_D 217 54962.03
54962 Site_D 217 54962.04
I'm looking to increase all index group, not just each element.
Thanks in advance,
John Ortiz
