Re: [R] compute values by condition in DF by rownames

Hi, I like the aggregate version. Here is an implementation with sapply and apply: > data X2 gbm_tcga lusc_tcga ucec_tcga_pub 1 gbm_tcga 1.0 0.14053719 -0.102847164 2 gbm_tcga 1.0 0.04413434 0.013568055 3 gbm_tcga 1.0 -0.200

Re: [R] compute values by condition in DF by rownames

Thanks JS I think aggregate function is better. Karim Le 17 févr. 2015 08:33, "JS Huang" a écrit : > Hi, > > I hope that someone can provide a better way to implement it. This is my > implementation. > > > data > X2 gbm_tcga lusc_tcga ucec_tcga_pub > 1 gbm_tcga 1.000

Hi, I hope that someone can provide a better way to implement it. This is my implementation. > data X2 gbm_tcga lusc_tcga ucec_tcga_pub 1 gbm_tcga 1.0 0.14053719 -0.102847164 2 gbm_tcga 1.0 0.04413434 0.013568055 3 gbm_tcga 1.00

[R] compute values by condition in DF by rownames

Hi All, how to compute only abs(value) > 0.2 of DF X2 gbm_tcga lusc_tcga ucec_tcga_pub gbm_tcga 1.0 0.1405371906 -0.1028471639 gbm_tcga 1.0 0.0441343447 0.0135680550 gbm_tcga 1.0 -0.2000397119 0.0389718175 gbm_tcga 1.0 0.
