    <p>How to select the rows from data frame which has a value over 1 in a specific column ?</p> <p>That's how my data looks like:</p> <pre><code>&gt; dput(head(tbl_comp[,-1])) structure(list(Meve_mean = c(7774.44229552491, 43374.1166119026, 585562.72426545, 3866.54724117546, 320338.197537275, 918368.01990607 ), Mmor_mean = c(39113.5325249635, 119476.157216344, 1296530.34384725, 23511.2980313616, 209092.538981888, 577355.581852083), Mtot_mean = c(23443.9874102442, 81425.1369141232, 941046.53405635, 13688.9226362685, 264715.368259581, 747861.800879077), tot_meanMe = c(258492586.999527, NA, NA, NA, NA, NA), tot_meanMm = c(246665241.110832, NA, NA, NA, NA, NA), tot_sdMe = c(35569170.0311164, NA, NA, NA, NA, NA), tot_sdMm = c(30522099.9189256, NA, NA, NA, NA, NA), Wteve_mean = c(10752.4381084666, 53658.8435672746, 715547.921685567, 3422.17220367207, 335384.199178456, 1013708.18845339 ), Wtmor_mean = c(29254.6414790837, 98804.8007431987, 1001344.20496027, 11541.8862121394, 217110.411645861, 571826.157099177), Wttot_mean = c(18681.9538387311, 73007.110928385, 838032.04308901, 6902.04963587237, 284695.433093058, 824330.175015869), tot_meanwte = c(278901499.672313, NA, NA, NA, NA, NA), tot_meanwtm = c(235415566.775308, NA, NA, NA, NA, NA), tot_sdwte = c(16743477.4011497, NA, NA, NA, NA, NA), tot_sdwtm = c(3922418.43271348, NA, NA, NA, NA, NA), diff_eve = c(0.72303994843767, 0.808331185101342, 0.818341730189196, 1.12985174650959, 0.955138012828161, 0.905949098928778), diff_mor = c(1.33700262752933, 1.20921408998001, 1.29478988086689, 2.03704122525771, 0.963070068343606, 1.00966976533735), diff_tot = c(1.25490018938172, 1.11530419268331, 1.12292428650774, 1.98331269093204, 0.929819510568173, 0.907235745512628)), .Names = c("Meve_mean", "Mmor_mean", "Mtot_mean", "tot_meanMe", "tot_meanMm", "tot_sdMe", "tot_sdMm", "Wteve_mean", "Wtmor_mean", "Wttot_mean", "tot_meanwte", "tot_meanwtm", "tot_sdwte", "tot_sdwtm", "diff_eve", "diff_mor", "diff_tot"), row.names = c(NA, 6L), class = "data.frame") </code></pre> <p>In this data there are three columns which I am interested mostly in:</p> <pre><code>diff_eve diff_mor diff_tot 0.7230399 1.3370026 1.2549002 0.8083312 1.2092141 1.1153042 0.8183417 1.2947899 1.1229243 1.1298517 2.0370412 1.9833127 0.9551380 0.9630701 0.9298195 0.9059491 1.0096698 0.9072357 </code></pre> <p>I would like to create new data frames selected by the value in each of those column. There should be 6 new data frames. Values below 1 in "diff_eve" column should be in new data frame, same goes to values above 1 = next data frame. Of course I would like to keep all of the columns from the data (tbl_comp).</p> <p>Let me show the example of the new data frame. Selection by the values below 1 in the column diff_eve:</p> <pre><code>&gt;newdata.frame diff_eve diff_mor diff_tot .. ....... ..... rest of the columns from tbl_comp. 0.7230399 1.3370026 1.2549002 0.8083312 1.2092141 1.1153042 0.8183417 1.2947899 1.1229243 0.9551380 0.9630701 0.9298195 0.9059491 1.0096698 0.9072357 </code></pre> <p>I hope some of you understand what I want to achieve.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
